Adjustment of Status - I-485

Hi guys,

I have a questions that I'm a tad bit confused about.

How long after you submit your paperwork do you receive your work permit?

My current work permit(from daca) is about to expire, and i would like to know long of a wait i have? I know everyone experiences are different, but it will sure help to understand the timeline.

Also how long does it take for them to schedule the interview?

My husband and I have known each other for 15 year, have been together for 6 years, and married for 3 years. We have a 9 year old, a 2 year old, and a 4 month old.

I don't know why I'm so nervous, but i guess it's the thought of someone judging you trying to tell you if your marriage is real or not. Trust and believe our marriage is real.

We didn't have a wedding, we just went to the courthouse and got married. A lot folks i read have big weddings or big garthering after their courthouse ceremony, we didn't.
We have joint taxes, light bill, gas bill in our names. We don't have a lease, because we're renting from my mother. But we do have an affidavit stating that we live with her. We have pictures as well and letters from our friends.

What other proof do we need??
