Dear T53147, thank you for your suggestion, this helped me a leap forward..
My previous employer agreed to offer me my earlier position at senior level as I approached them. Also, couple of job-placement agencies are willing to offer me job based on my professional expertise.
Now, the problem is to prove Employee-Employer relationship: http://www.h1base.com/visa/work/H1Be...Rule/ref/1577/
Any work-around is seemingly not possible at this moment, please help.
