Can I apply for a visa after the project is completed?

Generally speaking, visas can only be processed before entering the destination country or during the stay, and it is more difficult to apply for visas after working in the destination country. If you need to stay in the destination country after the completion of the project, you need to change or extend your visa through other legal channels, such as finding other suitable job types or meeting the requirements of investment immigration. The specific situation needs to be understood and adapted through the specific immigration policy of the destination country. It is best to consult foreign lawyers or professional immigration agencies for more accurate information and help.
