Portia,
Congrats on your engagement! I'm sure you must be very excited.
Is your fiance not working at all? If not, you may have a difficult time getting a fiance visa to come over and get married on. One of the big things they require is financial ability to support you before your wedding takes place. Financial support also takes the form of needing to prove that you will have accomodation.
If you are arriving in the UK with the intention of getting married and settling here in the UK, you will need to fill out a Fiance Visa to enter the country. You aren't able to work or seek work with this visa, but once you are married, you can apply for a spousal visa which will allow you to work.
Here's what we sent in:
1 - Completed application forms IM2A and IM2B (one for you and one for your intended)
2 - Two recent passport photos of myself attached to the IM2A form
3 - My valid, original passport
4 - My finance's valid, original passport
5 - Photographs of HIM and I together and copies of itineraries proving we had each visited each other and met
6 - A letter from my sponsor (HIM) stating that we had met and he was indeed intending to marry me, could not bear to be away from me, blah, blah, blah and that we were planning to live in the UK permanently and together
7 - My resume showing I had skills that should enable me to find work once we were married
8 - My fiance's lease showing we had accommodation
9 - A letter from my fiance's employer showing that he had income to support me until we were married
10 - A cover letter from myself stating that:
I was planning on arriving in the UK on or about 20th March
Neither of us had been married before and so no divorce papers were included
Neither of us had dependents so there were no forms for them included
My contact details (phone numbers, email, etc)
We had made initial contact with the registrar's office in Aberdeen and had a cleared the date and time with that office
11 - A money order for $382, $10 of which was for return express postage
12 - Bank statements for the past three months for both myself and my fiance (they had to call back and request this which delayed things by a couple of weeks)
It may also be useful to note that you will have to prove that you are living together as man and wife in order for your spousal visa to be approved. If he's living in the dorms and you in your own place, they aren't going to consider your marriage valid and my deport you. I would highly recommend going back to the Home Office website and reading up on this stuff.....I know it can be confusing but better safe than sorry later!
Best of luck!
