Stories like this one are play out every day, including here in East Texas.  Please, avoid people who are not licensed attorneys who claim to be immigration consultants, notarios, etc.  This is the unauthorized practice of law. 

Seek assistance only from Board of Immigration Appeals representatives or licensed attorneys, preferably with experience in immigration law.  Working with someone not familiar with immigration could lead to costly mistakes that could jeopardize your immigration case.
