text: i have an l1 visa but want to marry a us citizen.? i'm british have an l1 visa & am looking to marry my us fiance.anyone know if i can remain in the us to marry or if  i still have to leave & apply for a k visa? thanks as far as i know, after marrying a us citizen you can stay and wait for your green card. you'd have to go through several interviews before you get your green card.  my friend keep her f-1 status before she got her green card a year after marrying a us citizen. i believe the waiting period is different in each state - so the best is contact your local immigration office.
