Issue 1:The financial support requirement can be met by having a qualified joint sponsor (US citizen or Green Card holder living in the US). A joint sponsor has the same I-864 requirements as the primary sponsor/petitioner.
Issue 2: Your wife will have to show evidence of US domicile or the intent to re-establish domicile in the US. She will either have to move to the US ahead of you or she will have to show evidence of concrete steps taken toward re-locating to the US. You can show in-laws address as intended initial location.
No. You are not eligible to file under the 3 year rule.
I am Married to a U.S. Citizen | USCIS
"
Have been living in marital union with your U.S. citizen spouse during the three years immediately before the date you file your application and while we adjudicate your application;"
I would state both the petitioner and beneficiary names in the body along with the case number. I would just say that you wish to hold your case at NVC for a period up to a year. I would say you plan to continue at some point in the future.
Do not pay any fees or upload any documents at this point.
No reason to contact NVC now. Just wait until the I-130 has been sent to them.....then you can just let it sit for up to a year without contacting them if you want.
You can delay the process indefinitely at NVC by just waiting to upload documents and/or waiting to pay NVC fees. You must contact NVC at least every 12 months to keep the case alive. No need for an attorney.
Another vote to apply as soon as you are eligible. Otherwise, you could be waiting for a very long time for the I-751 approval (I say this from experience).
Medical emergency, threat to personal safety, Military deployment, etc. It must be an exceptional circumstance. Short notice Job relocation is the most common.
It's never too early to think about the dark hole of the I-751 (I'm not a fan of it).....that is your next step. Fortunately, it will get easier after that. ...much easier.
