two year later after the interview, her hu*****and has to send a letter to BCIS to prove this is a real marriage, so she can get real greencard,
I am sure that her hu*****and will not prove, so she has to find one immigration lawyer to deal with it.
I heard one lady married a US citizen in Taiwan, after they came to USA, they divorced, but that lady hire a lawyer to deal with it, the real greencard granted
