My two-year-old daughter is a Canadian citizen. I applied for a visit visa many times, but I was rejected. Can it be settled through litigation?

The so-called lawsuit means that you complain to their superiors, not really go to court.

In your case, they may suspect that you have an immigration tendency, so you won't come if you go to accompany your daughter, and your previous work permit is actually a disadvantage to you (whether you really worked there or not), which means that you want to stay there for a long time, otherwise why do you apply for a work permit?

You have to find ways to prepare more materials to convince the visa officer that you will come back. There is no better way.
