Key legal question
Whether a later Swiss naturalization allows a helplessness allowance claim to be assessed under the rules for Swiss nationals despite the claimant not meeting the earlier foreigner-specific insurance requirement.
Extracted holding
Yes. After naturalization, the claim must be assessed under the rules applicable to Swiss nationals; no minimum contribution period at onset is required for a helplessness allowance.
Extracted reasoning
Art. 6 LAI no longer contains the former insurance clause. For a Swiss national, entitlement under Art. 42 LAI requires insurance coverage and domicile/habitual residence in Switzerland, but not prior contributions at the time helplessness arose. The prior lack of qualifying insurance status at onset does not permanently bar reassessment once nationality changes.
