Thanks again, everyone.

I called Worldbridge last week and found out that yes, I will need to apply for a settlement visa before I move over there. (Thank you for the link, Izzysmum).

One thing that people may want to take note of is: I called the City Hall of the US state where we would like to be married and asked what paperwork he would need in order to marry me in the US. They told me that all he needed was his passport or other photo id with his current address listed on it(and if he had been married before, proof that the marriage has ended).

This is going easier than I thought! What a relief.

I do have some more questions though after reading some other people's responses about visas.

We had planned on marrying on a Saturday in the US, fly to England during the week and have a blessing ceremony in England the following Saturday. Is there a chance I would get my visa in a week? Can I apply in person and get it the same day? What is the standard waiting time, if any?
