our accountant put in a request for an extension I think you could use that letter to take to your interview and give to them. they know we don’t have any ssn to do those stuff so try that

Actually even you don’t have ssn, you can file joint tax return, which is that we did this year. You could have filed your joint tax return and at the same time applied for ITIN. But it’s a little too late to do that now i guess since your interview was scheduled. If you have other evidence to support your case, it should be fine, joint tax return is not necessary.

U can tell them that and u are working to make an amandment

I don't have it also , but we still file together.
