In order to get extension beyond six-years in H1B, your labor should be pending in DOL for more than a year.
You can get extension beyond six years if you have this. There is no provision that once the pre-approved labor gets approved, you will get the same benefit as you are utilizing someones else labor.
You need to get I-140 approval if you are looking to get the H1B extension beyond six years, and you are eligible to get 3 year extension, given that your I-140 is approved.
You are funny to say that "The substitute labor is already approved" becuase you cannot file I-140 if the substitute labor has not been approved.
Labordrags, I guess, so that pretty much rules out using the labor substitution.
If we applied PERM from scratch, does it take couple of months to prepare the application for PERM and then another couple of months to get approval?
His H1-B expires in Feb 2008 which means that the I-140 for the new PERM application needs to come thru by at least Jan 2008. At present there doesn't seem to be another option but are we going to be cutting it too close?
