I would like to draw your attention. As per H1B rules, there is no grace period. There is no question of jobs- man. You have already duly signed job offer and company sponsor to you and got approval from USCIS. In case there is no job, there no H1B. So, you have to make sure that, in case you are not able to pay tax as per your ETA- Labor Certification Wages, filed with USCIS, when applied your H1B, you will be found hard situation after 2 months (60 days). Legally, you are illegal in case if do not meet the USCIS rules, within 60 days and do not have pay stuff in your hand as per ETA minimum wages fixed and company duly signed while applied to H1B. Then, you are compelled to file sue against such company or immediately transfer H1 or back to school.

Now, the scenario is very strict and day by day, so-called company (consulting company) made able to enrolled their names into USCIS/DOL blacklist rigorously people are suing for them against pay stuff and tax matters.

Let me know, if you have any further information. Write me email, if you need more in detail in futures.

Good luck and Thanks
