This is where it gets tricky. Within this 3 years I need to get a new PERM approved by the new employer. So, say I set aside 1 year for the new employer to get all the internal budgeting approvals and initiate my GC process. Then it takes at least another 6 months (no attorney's file PERM within 6 months these days) to file the PERM. And, then say another 1 year to get the PERM result. So, this will take me 2.5 years into my 3 years limit. Now, god forbid, if the PERM gets denied due to clerical error. There is not time left for another try. Pretty much pack-up and leave.
