I came to US through company A on H-1B visa. I finished one project with them and currently on bench. They are paying me on bench. As per the employment agreement, I am supposed to give them a 15 days notice. Already they are holding more than 15 days salary.
Now I got an offer from company B and have applied for H-1B transfer. However I have not informed company A about this offer since I am yet to get the new petition number. I am planning to start working immediately with company B and inform company A that I will be quitting shortly (may be after I get the new petition number).
Is there any legal issues in my approach? The only reason I am doing this is because company A could not get me a project for more than one month.
Your suggestion is appreciated!
