My father (who is a PR) has filed I130 for my sister (unmarried child over 21) in June 2002. My parents have just moved from Illinois to Massechusetts. I would like to transfer the petition from Nebraska center to the Vermont center since Massechusetts falls under Vermont center. Does this transfer affect the timing to process the petition at all? I don't want to change the address if doing so can delay the processing. Please, give me some advice on this issue. Thanks.
