The portion of the I-140 application was not accurate as I understand now, however it is approved recently. Is it possible to ask for correction and thus let the case pending?
-No unless the approval was a USCIS mistake.
Also, I have two approved I-140 now, can the pending time of the previous I-140 be added for reducing child’s age when filing i-485?
-You only can count the I-140 pending time which you use to file I-485 for your child CSPA age calculation.
Those are unusual questions. Thanks for comments or directions.
