I wouldnu2019t say it re-sets the timeline, though there may be some delay.USCIS often does this for u201cload balancingu201d - because they feel they have more capacity at another service center.They should technically go in the queue where they would go if received at that new Service Center to begin with - if theyu2019re now working on May for your case type at the new destination Service Center and February at the original Service Center, and your case was filed in June, the new Service Center should get to your case when it gets to other cases filed with them in June - a month away or so.But the transfer and housekeeping (logging the case in as received at the destination Center, filing/organization etc.) often add an additional month of delay or more.
