Is there anything on the UKBA website (or anywhere else for that matter) that deals with this issue? I have been trying to find some sort of official stance on the matter but so far haven't managed.He can return to US before his marriage. But after he is married, he shouldn't leave the country until he has obtained his BRP (this is now in lieu of stamp/sticker in his passport, so he must have it). Otherwise he would face a big hassle trying to re-enter UK.
If you marry early in the 6 month period, I don't understand why you couldn't go on a 2 week honeymoon prior to coming back to the UK and applying for the spouse visa?
Or am I missing something?
