I am a US Citizen and I want to apply for my wife. Been married for 9 years. She comes and visits me on her visa waiver from NZ. What papers do I need to apply for her and how long would it take? Would it be quick and easy to apply for her while she is here on her visa waiver?
I generally discourage people from applying for a green card while they are here on a visa waiver type visa/entry. Call USCIS customer service for a list of the forms you will need. Generally speaking, these are relatively easy cases and should not require a lawyer.
