Thanks for clearing up the misunderstandings.
There are many factors, that go into the LC vs NIW and the CP vs AOS pathways. Here are my 5 cents
Heritage:
- if you are from a country with a consulate that doesn't have an overwhelming immigration workload, you definitely want to go with CP.
- if you are from the Phillipines, China, India and Poland, all countries with a tremendous family based immigration volume, you might be better off using AOS. (Waiting times at the consulate to get appointments and sometimes truly byzantine buerocratic hurdles might eat away from the time advantage of CP)
Practice location:
- If you are in a state that has a minimal processing time for the LC (old Denver region, ME, NH), it is possible to get an LC in a short time (5 weeks-1 year).
- who knows how PERM will play out. The DOL's history of f&^*%& things up beyond recognition makes me somewhat pessimistic.
- If you are in one of the nightmare LC states (mainly big states and the south), an LC might take more time than the 3 year waiver job)
Future plans:
- If your waiver job is in a reasonably attractive location, and you are planning to open your own practice, there is nothing wrong with going the NIW route.
- you can do the NIW thing using CP as far as I know. You can spend the 6 years that it takes entirely in H1b status and never file an AOS request.
- If your waiver job is in a location that you don't want to be buried in and you can't wait to get away from there, get an LC from a job other than your waiver practice.
Practice size:
- if you join a larger practice with a recruitment department and considerable financial assets, there is no problem getting an LC and I140 approved.
- if you join a small practice (2-3 principals), you might be better off using the NIW route. Smaller organizations undergo more scrutiny at the LC and I140 level than bigger ones. A statement of the CFO certifying that 'we have 450 employees and an annual income of $60m and are able to pay Dr X's measly salary' is enough to obviate the whole 'ability to pay' song and dance.
Practice structure:
- if you join a large multispecialty group and you will remain an employee forever, an LC based I140 is no problem.
- if you join a small practice with intent to become a partner after a year or two, you might want to consider NIW. (It is problematic if you are a major shareholder/officer of the corporation sponsoring you for a GC)
'How much do you hate your employer' factor:
- if you join a small practice and your friendly countryman who offered to 'help you out' turns out to be a ruthless slavedriver, you want to keep your exposure at a minimum. With a NIW you can piss on his table at 3 yrs and 1 day without worrying about him withdrawing an I140 or sharing - the 'dirt' on you with the CIS enforcement division.
- a pending immigration case weakens you during salary and partnership negotiations. If you work with the usual crooks that run group practices, a pending I140 reduces your market value considerably.
