hi friend

very serious problem

best thing is that ask help for human rights, they can guide you properly.

many people, many openions, so take action by your self.
if there is travel ban, no need to worry, actually it is good for you. please dont be hopless. strugle hard to reach out to labor court and human rights. specially human rights. i am sure they will help you and they may send your case to ministry of interior and they may change your sponsorship temperorlly period till you case is solved.

or if you have any relative who can take gurantee to the bank.

dont hopless - there is alwasy solutions to any matter.
