I am trying to file I485 by myself. On the "Affidavit of Support/Employment Letter" part, do I also need to file a "Affidavit of Support" for my wife? I was told by a friend to use I134. But it seems to me that I134 is for US citizens to sponsor someone to enter the country. Do you know which form I need to use? Do I really need to have that affidavit for my wife?
Thanks and best wishes,
