In Texas, only US citizens can update their addresses and renew DLs online. Otherwise, Green Card holders have to ALWAYS renew and make changes in-person only. We took wife's Naturalization certificate and her US passport.
Good luck......You could get the interview at any time since those estimates are very inaccurate sometimes. Hopefully, your N-400 will push the I-751 soon. It did in our case.
Marriage is irrelevant....US citizen children are irrelevant. If they entered the US without inspection, they can't stay.....and bans are real unless waivered.
I heard the government has increased the incentive to self-deport to $3000 along with a ticket to home country. This administration is serious.
A spousal visa, processed through USCIS, NVC, and the consulate, could take about 2 years. The I-130, alone, at USCIS, will take a year or so for approval.
My decision process for a spousal visa:
Step 1: Decide when you want to re-locate to the US.
Step 2: Decide if you want to try the DCF route (if petitioner is living outside the US) or if you want to file normally thru USCIS.
Step 3: For DCF, contact the consulate and request they process the case. If approved, they will give you instructions for filing directly thru them. For normal consular processing, you file the I-130 thru USCIS. Once you file normally thru USCIS, you cannot later file DCF.
If filing a normal I-130 case through USCIS, see this guide:
No... ...If you file an I-130 online to USCIS, you lose DCF........DCF means "Direct Consular Filing"......Filing online to USCIS means consular filing....but not DIRECT Consular Filing. With DCF, everything bypassess USCIS.
But, for consular filing (filing an I-130 thru USCIS), you would put that your consulate is Montreal....but that is not DCF.
Be aware that you cannot go the DCF route once you have filed a normal I-130 with USCIS. Also be aware that Montreal is notorious for their scrutiny of US domicile.
Of course, they can....if the consulate officer believes the petitioner or joint sponsor has sufficient income or assets to prevent the immigrant from becoming a burden to taxpayers.
