Each state has a Labor board. You will find that they are pro-employer.
lucky for you, DOL is vigilant in cases that involves foreign workers. best is to talk to a lawyer who practices labor laws.If the former employer hold your salary, which specific DOL agency I can go and complain.
Like if there are any wages problem in ON, the ministry of Labor handles that. Is it the same process here too?
Will appreciate your responses/help.
