We arrived 30 min early and were called in together exactly on time, 8:05am.
IO was a younger woman - guessing around 35, very serious and business like. Did not smile at all.

After swearing us in, she started by asking for documentation of joint property, etc.
We gave her 2017 joint taxes, checking, savings accounts, auto insur, credit cards, health benefits, engagement ring insurance, AAA account. All our information was organized and indexed.
She asked about utility bills, but they had either my or my husbands name, not both.
Then she asked about joint lease or mortgage, but our coop is only in my husband's name since he owned it before we met. She was satisfied with that answer and he told her I am the beneficiary in his will.

During this time, she was looking down at the docs, making lots of notations and interspersing basic questions like verification of birthdays, occupations, my husbands children from his prior marriage. She quizzed me on their ages and if I met them and how we all get along. She asked my husband my future plans and me about his job; also each of us how many times the other has been married.

She asked how we met but wanted my husband to reply, not me. She didn't seem to be looking for long answers. He told her We Chat, then she asked him if he likes Chinese women! he said his previous girl friend was also Chinese.
She asked when we got married and where, and who attended the wedding. It was just the two of us in Las Vegas.
She asked me when my husband was divorced and him when he got separated and why he waited so long to divorce from being separated (over 5 years).

Lastly, she went through the yes/no questions.
The entire interview took 30 minutes after which she told up everything looks good but she just has to check a few things, and that we should receive notification in 3-6 weeks.
Although she didn't keep any additional documentation, she said we should keep the binders for use in getting the permanent green card. This is because she commented that our original application contained enough information. She compared the size of our file compared to a typical file. Ours was double the thickness!
She didn't look at any additional photos, vacation receipts, etc. - even though we brought at a half binder full.
We told her that my drivers license expires on 4/16 and she seemed to think we may have the GC by then.

Also, we have a 29 year age difference, but she did not ask one question about that. We believe that between the evidence we provided in advance and our responses, it is clear we are truly a couple.

Feel free to ask questions...
