Could anyone know what's an average time frame for obtaining EAD if someone initiates his GC process thru EB-3 being on TN at this time? Can I-140 & I-485 be applied concurrently on EB-3? Also, if a recognized assessment service in US counts a 3 years foriegn BS equivalent of 101 credits (+ 10 more additional credits from insititutes in Canada) to a US degree along with 10+ years of experience, would that be considered enough for EB-2 qualification?
