I am planning to get marry in December, 18th, 2016 in Dak Lak, Vietnam at girl's house first and than the my house in Ho Chi Minh in January. I have a question about what I should do and what type of steps needed in order to bring my wife to the U.S later on. I am planning to get the single affidavit in America and then go to Vietnam. What other steps should I take either in America or once I come back to Vietnam. Please help.
