A bit of a basic question but, if an individual working in the US on an H1B Visa decides to marry a US Citizen, how will it affect their job status? Will they have to quit their job, go back to their country of origin and return to the US on a Marriage/Fiance visa once that process is approved?
I did this. I was on H1B and wife is American. For starters, you don't have to leave the country for anything. You and your wife will apply for Green card and Change of status. But this is after marriage.
Anyone in this situation is strongly encouraged to consult an immigration lawyer and spend the time to give them all the information you have, and listen to all the caveats they list. Yes, it will cost you a kilobuck, but potentially save you a lot more kilobucks, a lot of time and a lot of anxiety.
