Thanks guys.
I am hoping to see all of you in I-140/485 forum. Especially pipladi, zbcx, and insat.
Jolpot,
There are many different state labor dept (SESA) under Boston DOL like MA, CT, MA, Maine, Vermont, RI etc. You SESA will be in which state you file your labor certification.
PD is the Priority date. The date SESA received your application and assigned you a case number.
Good luck
