Time frame to get the final judgment after winning the first stage of a labor case

Hello everyone,

My company terminated me without any reason and refused to pay me my dues. I put a case against them and got first judgment in my favor.

Now we both parties have 30 days to appeal. How will I know if the company appealed against the judgment? Also, I got an offer letter. Is it possible to cancel my visa at this stage?

In case the company appealed, how much time further will be required to reach the final judgment?

Please give me your best advice. It will be a huge help.
