Need some help.

Right now, I am in OPT and just  filed for OPT extension with my current company. Now another comapany is also offering me a job. I like the job. But the problem here is I have just filed for OPT extension may take 30 - 90 days to get approved. The  second company may not wait for me more than 30 days at most. I talk with my advisor, she told me that I can't change a company when I am in the process of OPT extension.

Need some suggestions on it.

continue what you are doing, tell the other company to wait. if they like you, they will. if they don't they'll move on and so will you with your current job.
