NOTE * We don’t received the first letter of the bio-metrics appointment, so we had to call and told they to re-schedule, they told us when we call that I was schedule and supposed to put my bio-metrics in 06/03/2018.

And yes, I know it was too fast, Sincerely me and my wife did not expect that. I came to USA in November, we have like 2 years together.
She is (US Citizen – born here) and is the petitioner, and we are married since finals of March, we are living together before married, like 2 month before. We live in an apartment with her litte daughter / My stepdaughter.

We send all the Copy´s documentation that our lawyer told us, like ( Married certificate, both birth certificate + (translation) , both passport, SSN of her, 1 Sponsor Affidavit + my wife Affidavit, Medical exam, payment stubs of her and the other sponsor, a Letter of my wife job about the range Salary etc etc. we have more payment stubs of last 2 month and a Letter of salary range of our sponsor, and all the original Documentation that we send before mentioned.

She work for a Hospital and I am a Technology Guy with a good Professional certifications on the Technology field that have a good salary range here in USA.

 So the thing is, like you see, I did not received the EAD yet, and I don't have any ID from USA, so the problem is that we don´t have bills together, because i need any ID for all, we just have her bank account with me like beneficiary together and some correspondence that i received in the house, we can’t put the lease together because is a low income, but we have photos in my country in her last trip the last year, in many touristic places like, beach, river, National parks, party, the wedding photos and common photos here with the family.

So, we don't know what expect about the interview we don't know if the quickness of the interview is good or bad, because they can tell us that we don't have enough proof together, but they didn't issued me a valid ID for make this movements.

Do we have to worry about?
Can somebody tell us any advice, please??

Thanks in advance and sorry for Any typo.

Regards!!!!
