Sorry to be just now seeing this:
There are some websites out there (sorry, I don't have the bookmarks) full of tips from people doing immigration on a K-1 Fiance(e) Visa.
Having done this myself (brought fiance over from Canada) (well, now, ex-husband)....
Overdue everything in your application package.
They want to see EVERYTHING. Ours was 400 pages. And took me 2 months to assemble everything.
They want photos of you with each others family members. They want photos of you in each others country (Example: Us in front of major stadium in his country, in West Edmonton Mall, major lighthouse in Michigan, photo of him and my mom, photo of me with his family).
They want correspondence. Yes, print out those Instant Messages. Make copies of those Birthday cards. Copies of phone bills.
They want proof you can support both of you, so yes, paystubs, bank statement, letter from your bank saying how long you have had an account and a years account history. Letter from your employer saying how long you've been employed, how much you make.
Trust me....they want EVERYTHING. And it is easier to give them too much info than not enough.
It took 4 months to get approved. Then more time for him to do the Medical Exam, Interview, etc.
It's a time consuming and expensive process, but worth it if you really love the other person.
Good luck to you.
PS: Be sure to keep a copy for yourself of the entire package.
