If she can apply under the 5 year rule, I would not file based on the 3 year rule. This is what we uploaded for my wife's N-400 based on the 5 year rule:
5 years Tax transcripts
Proof of my 1st marriage Termination
Proof of Wife's 1st Marriage Termination
Wife's Green Card
Our Marriage Certificate
Under the 3 year rule, it would have a been a LOT more.
Why did your husband enter "Adjustment of Status" on the I-130 if he submitted the I-130 from Canada? The I-130 is just the first part......everything is is slow, sadly.
and there could be an additional issue. If the petitioner entered Adjustment of Status on the I-130, the he will have to submit an I-829 to move the approved I-130 to NVC (if OP opts for consular processing).
OK. Then you submit the I-485, I-131, and I-765. You have to stay inside the US until you receive advance parole. ....else, you will abandon the I-485.
Are you aware that, once you submit the I-485, you cannot work inside the US or leave the US for up to 6 months or more?
Yes, you will receive a receipt notice for the I-485.
Note: The I-485 is for applicants who live inside the US.
You don't need a joint sponsor if your current income is sufficient for your household size. Just be prepared to show the consulate officer evidence of your CURRENT gross income.
