Deep dives
Citizenship Act §3(1)(b) · Bill C-71
First-generation born abroad are citizens by right. Bill C-71 (in force 2025) restores citizenship to beyond-first-generation descendants where a substantial connection test is met. We assess your eligibility, file with IRCC, and represent you on RFEs.
British Nationality Act
British nationality law is famously intricate. Crown service, consular registration, and double-descent (grandparent) routes each open under different sections of the BNA 1981. We map your exact fact pattern to the right section.
