I have been a holder of GC for 2 years. I have obtained the GC via my employment. I will be getting merried in a few months to a US citizen, and would like to know what I am expected to do by the INS. Do I need to contact them for any reasons? I will be changing my name etc. Also, do I need to do some sort of filing...? I understand that to be able to apply for Citizenship, GC holder must wait 5years. .... I am actually a citizen of one of EU countries, and am not really in "need" of US citizenship. I am just wanting to follow the rules in the USA etc.
