Get a lawyer. Like yesterday.
Hide your passport, IDs, bank books. Have a stash of money for emergency somewhere safe. Clothes and valuables too. Again, yesterday.
Build up support. Emotional support. A circle of friends. Do not isolate yourself.
Inform yourself of your rights. Do not ask locals.
It is easy as pie to divorce. You can go to 711, buy a divorce contract and sign, file and it’s over. All you have to do is agree. Hence, if she wants to force your hand or threatens to force your hand, it is manipulation, psychological torture.
Remember that after you sign, you lose all rights. If it is not written in the divorce contract, it does not exist.
That said, depending on her connections and desire, she can make your life a living hell. We are talking accusing you of abuse or battery, robbery, etc. So, at this point, under no circumstances go to bed with your wife “for old times sake…to rebuild our relationship”. It’s a trap.
Regarding your visa, yep, it is a tough one. If you have a job that can give you a work visa, you may stand a chance, though under current pandemic circumstances it is not certain. And if you do not have a visa, you cannot stay and fight for your rights. So do not sign anything UNTIL you are set, meaning you have your visa issue covered. For starters.
