So my fiance and I just need to go to the immigration office in Detroit and submit the applications? What's the fee for the applications?
The fee is $75 for the sponsorship and $475 for the application. Both of these must be paid up front. Once you are approved there is a $490 Right of Permanent Residence Fee which must be paid before the PR visa can be issued. You can pay it with the application or wait until later. Waiting until later may cause a delay of a month or two.
You can expect to pay about $250 to $350 for a medical exam, some blood tests and a chest x-ray and their associated paperwork. That will be paid to the doctor and lab(s), not to the government.
Don't go to the office in Detroit for this. The application gets sent to Mississauga, Ontario, who processes the sponsorship part. Once this is approved, they will forward the application to Buffalo. If Buffalo's case load is too heavy, they may transfer the file to one of the other consulates in the U.S. If an interview is required it will probably be in Detroit if that's what you prefer. It doesn't appear that interviews are done in Buffalo.
As Allison said, it will take you some time to prepare the application. Aside from about 30 pages of forms to fill out, they also want to see evidence that your relationship is genuine and developed over a period of time, so that they are assured that yours is not just a "marriage of convenience" entered into for immigration purposes. They'll want photographs, phone records, records of emails, receipts, etc., showing the times you were together and the times you communicated before the marriage. They'd also like to see wedding invitations, receipts for a reception, photographs of the ceremony, evidence of a honeymoon, etc., whichever of these applies. It's going to take a bit of time and effort to get all this stuff together.
