My fiance didnt have too bad of an experience, because i called and ask for the head of the consulate to ask her help to ensure he had all the correct forms.
I asked that if he needed help please help him and they did. My worst mistake was hiring a so called immigration lawyer. I tell all who are starting out dont pay a lawyer your money if immigration wants to deny you they can and a lawyer cant help you. The lawyers will lie to you and make empty promise that they cant fulfil. I give the consulate in Tunisia for our case a thumb's up.
