I agree with BugsBurger. The couples were married way before their green card. The wife got a green card (E27) based on the husband's (E26). Now the husband is trying to file as a married person to a US citizen because the wife is already a US citizen.
By the way, they had a paid consultation with an immigration lawyer and the lawyer told 5-year rule. But i agree with BugsBurger because the USCIS manual does not indicate the category. So as long as the wife is a citizen for 3 years, a husband is LPR for 3 years and the couples are in a marital union for at least 3 years they should be fine. I was surprised even immigration lawyers do not read the policy carefully.
Do you have suggestions about an immigration lawyer who is competent enough to give legal advice?
