If you find new work place and the job you are going to be engaged in is the same kind of work you did in the former company, you will not lose the visa.
In this case, if you are not sure if you can work with the visa, you should apply for “Certificate of Authorized Employment”.
If you don’t work for more than 3 months without any valid reason, you will be the object of cancellation of visa.
Your visa was issued since it needed to work in the company that you are allowed to work in, and quitting job means that there is no activity for which the visa was granted.
In this case, you can’t say you are allowed to stay here until the expiration date of your visa.
Please be careful.
