Myanmar nationality law currently recognises three categories of citizens, namely citizen, associate citizen and naturalised citizen, according to the 1982 Citizenship Law. Citizens, as defined by the 1947 Constitution, are persons who belong to an "indigenous race", have a grandparent from an "indigenous race", are children of citizens, or lived in British Burma prior to 1942.Under this law, citizens are required to obtain a National Registration Card (နိုင်ငံသားစိစစ်ရေးကတ်ပြား, NRC), while non-citizens are given a Foreign Registration Card (နိုင်ငံခြားသားစိစစ်ရေးကတ်ပြား, FRC). Citizens whose parents hold FRCs are not allowed to run for public office.
