need help regarding re-entry to US on B1/B2

[walkinclouds]

I'm a doctor by profession, currently on 10 yr multiple entry B1/B2 visa residing in US. I'm working as a research associate, voluntarily on a
non-stipendiary basis( no pay). My I-94 is expiring in october first week. Going to India and re-entering US, leaving the project will cost me a lot, both financially and careerwise. In order to circumvent this, is it wise to go to Canada and then re-enter US within a couple of days? Since I have a
10 yr multiple entry visitor's visa, submitting I-94 when i leave US and going to canada and coming back to US again as a fresh entry, is it considered safe and within legal limits? The law says that you have to leave US after the I-94 expires, does it mean you have to return to your home country or is it just you have to leave US(may be go to a different country) and then return again? Would really appreciate if anyone could kindly suggest whether I would be safe doing this? You can mail me at walkinclouds@gmail.com
Thanks in advance.

Many intelligent beings got the same idea as you did just now to extend their stay in the US. I think most of them failed. Some got into some serious trouble as you do not get a new I-94 if you goto Canada and come back by road. I dont have a confirmatory answer about what happens if you do this by air. This is what I have gathered from previous posts. Moreover, for an alien, the law says that you must stay outside the US more than inside if you hold a B1/B2 visa, and you are clearly violating this. I am sure you will be pulled into some serious questioning at immigration about why are you re-entering so soon after a recent stay on your visitors visa. Finally, its your call.

On a different perspective, since you are working on a non-stpendary basis, I am taking a wild guess that you work for a medical school, university or some kind of a non-profit organization. If that is the case then why dont you ask your employer to apply for a H1 visa for you. Remember, if you are working in one of such institutions or organizations, you are H1 cap exempt.
