Matter of Nejat Ibrahim RUZKU, Beneficiary of a visa petition
filed by Abdalla Ibrahim Ruzku, Petitioner
Decided March 29, 2016
U.S. Department of Justice
Executive Office for Immigration Review
Board of Immigration Appeals
Direct sibling-to-sibling DNA test results reflecting a 99.5 percent degree of certainty
or higher that a full sibling biological relationship exists should be accepted and
considered to be probative evidence of the relationship.
FOR THE PETITIONER: Howard R. Davis, Esquire, Santa Monica, California

Counsel
AMICUS CURIAE: American Immigration Lawyers Association1
BEFORE: 	Board Panel: 	NEAL, Chairman; ADKINS-BLANCH, Vice Chairman;
MANN, Board Member.
MANN, Board Member:
In a decision dated September 17, 2012, the California Service Center
Director (“Director”) denied the Petition for Alien Relative (Form I-130)
filed by the petitioner to accord the beneficiary preference status as his
sister under section 203(a)(4) of the Immigration and Nationality Act,
8 U.S.C. § 1153(a)(4) (2012). 	The petitioner has appealed from that
decision. 	Counsel for the Department of Homeland Security (“DHS”)
opposes the appeal. 	The record will be remanded for further consideration
of the visa petition.
In this case we must decide what the evidentiary value of direct
sibling-to-sibling DNA test results should be and whether the Director may
choose not to consider such evidence. 	In visa petition proceedings, the
petitioner bears the burden of establishing the claimed relationship by a
preponderance of the evidence; that is, he must show that it is more likely
than not that his claimed sibling relationship to the beneficiary exists.
See Matter of Pagan, 22 I&N Dec. 547, 548−49 (BIA 1999). 	We review

all questions arising in visa petition proceedings de novo. 	8 C.F.R.
§ 1003.1(d)(3)(iii) (2015).
The petitioner submitted delayed birth certificates for himself and the
beneficiary, along with an undated family photograph and an affidavit from
two persons asserting that they are relatives who have knowledge of the
sibling relationship. 	The birth certificates, which reflect that the petitioner
and the beneficiary were both born in Eritrea to the same father and mother,
were issued more than 25 years after their births. 	The petitioner was
advised 	by 	the 	United 	States 	Citizenship 	and 	Immigration 	Services
(“USCIS”) through two Requests for Evidence that this evidence was
insufficient to establish the claimed relationship.
In response, the petitioner arranged for sibling-to-sibling DNA testing
with a facility accredited by the AABB (formerly the American Association
of Blood Banks). 	That facility provided its DNA report directly to the
USCIS. 	The report stated that the probability of the petitioner and the
beneficiary being full siblings is 99.8114 percent. 	Accordingly, the report
concluded that “it is very probable” that they are full siblings.
In denying the visa petition, the Director determined that the petitioner
did not establish that the beneficiary is his sibling. 	She declined to give
persuasive weight to the delayed birth certificates, the single undated
family photograph, or the relatives’ affidavit, which did not reflect personal
knowledge of the circumstances surrounding the births of the petitioner or
the beneficiary. 	The Director also afforded no weight to the DNA test
results. 	Finally, she did not indicate whether she assessed all the evidence
in its totality.
On October 1, 2014, we requested supplemental briefing from the
parties 	regarding 	the 	evidentiary value 	of 	sibling-to-sibling 	DNA 	test
results. 	Shortly 	thereafter, 	the 	USCIS 	issued 	a 	policy 	memorandum
regarding sibling-to-sibling DNA test results, entitled “DNA Evidence of
Sibling Relationships for Service Centers, Domestic and International Field
Offices.” 	USCIS, 	DHS, 	PM-602-0106 	(Oct. 	17, 	2014), 	reprinted 	in
91 Interpreter Releases, No. 42, Nov. 3, 2014, app. III at 1995. 	The
memorandum stated, among other things, that the USCIS “may not afford
any evidentiary weight” to sibling-to-sibling DNA test results and will only
consider parent-child DNA test results for each claimed sibling with a
claimed common parent.2 Id. at 2−3.
2 We are not bound by policy memoranda issued by the DHS. See Matter of Arrabally
& Yerrabelly, 25 I&N Dec. 771, 776 n.4 (BIA 2012) (stating that policy set forth in DHS
memoranda “is entitled to respect to the extent it has the ‘power to persuade,’ but it is not
binding” (quoting Christensen v. Harris County, 529 U.S. 576, 587 (2000))).

The USCIS filed a brief citing to the policy memorandum and stating
that direct sibling-to-sibling DNA testing is not sufficiently reliable to
establish the claimed relationship.3 The memorandum indicates that the
USCIS 	“learned 	that 	there 	is 	no 	universally 	accepted 	standard 	for
relationship 	probability 	in 	sibling-to-sibling 	DNA 	testing” 	through
consultation with its scientific resources, including the DHS’s Science and
Technology component, the National Institute of Science and Technology,
and the AABB. Id. at 2. However, it cites no published sources to support
its conclusion. 	The memorandum also notes the continuing need for
research to ensure that a set threshold number “will not exclude valid
sibling relationships.” Id. at 2 n.3.
The petitioner and 	amicus curiae filed briefs urging us to 	accord
probative value to direct sibling-to-sibling DNA test results where such
results reflect the scientific community’s accepted level of certainty of
99.5 percent or higher. 	They further argue that even DNA test results
reflecting a lower level of certainty should be considered in combination
with other evidence submitted to prove the claimed relationship. In support
of its position that a 99.5 percent certainty should be considered probative
evidence, amicus included information that referenced published scientific
studies.
In order to be probative, evidence must tend to prove or disprove an
issue that is material to the determination of the case. 	See Probative
evidence, Black’s Law Dictionary (10th ed. 2014). The USCIS’s statement
that sibling-to-sibling DNA testing is not sufficiently reliable to establish
the relationship is not adequately supported. 	The October 2014 policy
memorandum explains that the scientific community does not agree on a
particular 	statistical 	probability 	that 	conclusively 	proves 	a 	sibling
relationship. However, this does not establish that sibling-to-sibling testing
is universally unreliable and that the 	results of 	such tests should be
completely excluded from consideration.
According to a forensic DNA expert whose affidavit was submitted with
the 	amicus 	brief, 	“The 	statistical 	and 	mathematical 	methods 	used 	to
evaluate all of the different kinships are reliable, well established, and
3 There is no dispute that DNA testing between both siblings and a claimed common
parent is the best evidence to establish a biological sibling relationship. Such testing has
long been accepted by the USCIS as conclusive of the parent-child relationship. 	See
generally 	Vol. 	9, 	Foreign 	Affairs 	Manual 	§ 	601.11-1(A)(a)(2) 	(CT: 	VISA-3
Nov. 18, 2015) (previous location: 9 FAM § 42.44 note 1 (CT: VISA-2188 Oct. 3, 2014))
(stating that DNA “test results reporting a 99.5 percent or greater degree of certainty”
may be accepted by consular officers as “sufficient to support a biological relationship
between a parent and child in visa cases”). 	There are circumstances, however, where
such parent-to-child testing is not possible.

uniform throughout the industry. 	What has not been established is the
determination of the level of statistical probability that is convincing of
a non-parentage relationship . . . .” 	The USCIS has not refuted this
statement.
The USCIS’s policy of barring consideration of any sibling-to-sibling
DNA test results appears to be based on a concern that some results may
reflect a lower level of probability than 99.5 percent, even where there is a
true biological sibling relationship—in other words, that there is a risk of
“false negative” test results that could lead to the denial of some visa
petitions. 	We acknowledge this concern but do not believe it justifies
the overly broad position taken by the USCIS that it will not accept
sibling-to-sibling DNA test results or give them any evidentiary weight,
even when they reflect a strong degree of certainty that the claimed
biological sibling relationship exists.
As a comparison in this regard, we consider the evidentiary weight
accorded to birth certificates. Birth certificates issued at or near the time of
birth are generally accepted as highly probative evidence of a parent-child
relationship. 	See generally 8 C.F.R. § 204.2(d)(2) (2015). 	On the other
hand, because of the potential for fraud, birth certificates that reflect a
delayed issuance may be given less evidentiary weight and “must be
evaluated in light of the other evidence of record and the circumstances of
the case.” Matter of Bueno, 21 I&N Dec. 1029, 1033 (BIA 1997); see also
Matter of Ma, 20 I&N Dec. 394, 397 (BIA 1991); Matter of Serna, 16 I&N
Dec. 643, 645 (BIA 1978). 	Unlike the sibling-to-sibling DNA test results,
however, the USCIS does not decline to consider timely issued birth
certificates simply because some petitioners may not have them or may
submit fraudulent birth certificates. 	It is likewise not logical for the
Director 	to 	decline 	to 	afford 	any 	evidentiary 	weight 	to 	probative
sibling-to-sibling 	DNA 	test 	results 	merely 	because 	some 	results 	may
not have achieved the same level of probative value.
We 	acknowledge 	that 	DNA 	testing 	for 	siblings 	is 	different 	from
such testing between a parent and child. 	Nevertheless, the arguments
and 	scientific 	information 	presented 	on 	appeal 	persuade 	us 	that
sibling-to-sibling DNA test results reflecting a degree of 	certainty of
99.5 percent or higher should be afforded some evidentiary value. 	Giving
consideration to such test results would be in accord with the apparent
consensus in the scientific community that they provide probative evidence
of 	the 	biological 	relationship. 	We 	therefore 	conclude 	that 	when 	an
AABB-accredited facility has determined, from direct sibling-to-sibling
DNA testing of full siblings, that a 99.5 percent or greater probability of the
sibling 	relationship 	exists, 	the 	test 	results 	should 	be 	accepted 	and
considered to be probative evidence of the claimed relationship.

However, 	we 	do 	not 	hold 	that 	sibling-to-sibling 	DNA 	test 	results
reflecting any particular percentage probability will alone be sufficient to
establish a claimed full sibling relationship.4 Rather, we would generally
expect that other evidence of the sibling relationship would be submitted
and that all the evidence, including DNA test results, would be considered
in its totality. 	The weight to be accorded any particular DNA test results
will depend on the degree of certainty that is reflected in those results.5
In this case, the petitioner submitted sibling-to-sibling DNA test results
showing that the probability that he and the beneficiary are full siblings is
99.8114 percent. These results should therefore be accepted and considered
by 	the 	Director 	to 	be 	probative 	evidence 	of 	the 	petitioner’s 	sibling
relationship to the beneficiary. Accordingly, we will remand the record for
the Director to consider all of the evidence presented in support of the visa
petition, including the sibling-to-sibling DNA test results, and to determine
whether the petitioner has met his burden of establishing the claimed full
sibling relationship by a preponderance of the evidence. 	On remand, the
petitioner may be given an opportunity to present additional evidence.
ORDER: 	The 	record 	is 	remanded 	to 	the 	Director 	for 	further
proceedings consistent with the foregoing opinion and for the entry of a
new decision.
4 We note that the scientific probabilities set forth in DNA test results are different from
the legal standards that generally apply to the burden of proof in visa petition cases. The
forensic DNA expert whose affidavit was submitted with the amicus brief points out that
the courts have not yet set the bar on what statistical probability is necessary to prove a
biological relationship, but he states that “high probabilities can be trusted and low
probabilities should be viewed as non-confirming.” 	Other evidence offered by amicus
from the United Kingdom indicates that DNA test results of 90−99.99 percent are
considered “[v]ery strong evidence” of the sibling relationship but that results of
10−89.99 percent would be considered “inconclusive.” In addition, the DNA test result
report that was submitted in this case suggests as a guideline that a probability of
90 percent or greater should “support” a claim of a full sibling relationship; 98 percent or
greater should “strongly support” the claim; and 99 percent or greater should “practically
prove” the claim.
5 There may be a stronger need for additional evidence in the case of half-sibling
relationships. The scientific information submitted by amicus indicates that half-siblings
share only 25 percent of their DNA (unlike full siblings who share 50 percent of their
DNA) 	and 	that 	their 	relationship 	to 	one 	another 	is 	“genetically 	identical” 	to
that of other second-degree relationships, such as those of grandparent-grandchild and
aunt/uncle-niece/nephew. Thus, while DNA test results might reflect that the parties are
biologically related, additional evidence will be needed to establish, by a preponderance
of the evidence, which of those genetically similar relationships, in fact, exists.
