I might get laid off. My labor is pending and I will apply for B1/B2. In the mean time if my employer recruits me back again, will I be able to continue with my PERM and rest of the green card process? Do I have to start from the beginning?
There is no easy answer. It could be argued that the employer laid you off so the permanent job, which is the basis of the green card is gone. Hence, the process is fatally interrupted. Generally speaking, I think you should be able to continue.
