techniquely they will link your 485 to the latest 140 approved, automatically done by computer----i read it somewhere from someone who called the USCIS employee (not phone center).

however, in real life, many mistakes could happen so it's not guaranteed.
Some lawyers could help you do this but they will charge you too.

I believe you will win the case eventually in the worst case senario. so it really depends what risk you wnat to take.

If you simply call some representative from the phone center, they will say no if you want to relink
