I mailed my I-130 to the Phoenix lockbox as directed on the instructions. Does anybody know what service center the I-130 would go to after everything is finished at the lockbox? I would like to track the timelines at the correct service center.
It will be routed based on internal rules with USCIS. There's no way to know for sure where the I-130 will end up until you get the receipt notice (NOA1), which will state the service center.
Odds are Nebraska right now, but nothing is guaranteed.
