hello everyone..me and my wife submitted our inland sponsorship application a week ago..We sent the letter of solemnization instead of the marraige certificate since we didnot have it at that time..i was reading on the forums that if you send just the letter of solemnization you have to include a cover letter saying you will send the marraige certificate later..unfortunately we didnot know this at the time of our submission hence we didnot include a cover letter..now the good news is that we received the marraige certificate today and will be sending it out by tomorrow and request them to attach it with our original file..my question is- is there any possibility that they might return our application as incomplete just cuz of the letter of solemnization? thanks in advance!!
