I'm sure that I've prepared the I-864 properly and have adequate docs to show that I meet the income requirement. I'm just wondering when to expect any sort of Employment Authorization after submission. It depends on where you file. My experience is that my clients obtain theirs in a week or so. I have had one take as long as 60 days - but it was an unusual case.
Different offices have different processing times.
My fianc is in the US on OPT, but his status will change to H-1B in April. We are going to get married next week. He will not apply for H-1B visa. You should be very careful to go home before your visa waiver expires. He'll need to apply for you to come join him as an H-4 derivative beneficiary.
