so here is our situation filled initially in f2 category for unmarried son while mom was permanent resident in 2002, but got married(2005) before she became citizen(2007). USCIS took 2 years(now 2009) to reply to us that we need to file again instead of just status change to F3 category and that we lost the initial priority date!!! is there any other way we could get the initial priority date of 2002? 2nd question is there anyway mother and brother can file for the same person? just in case as a back up plan?
