How to get onsite/abroad opportunities?

I was supposed to go to Canada for my PG during Fall22 but my student visa got rejected. I had left the previous organisation (WITCH) due to that in July 2022. Later, I got a new job as a Python SDET/QA Automation role. Currently, I am content with the job but sometimes I will think I should try again for Fall 23 but now I am wondering if I get an onsite opportunity directly via some employer. Which kind of companies do such hiring? PS: Working in an average size Fintech company based out in Noida and overall work experience is 4.5 + years.
