As you have completed ITI COPA then you can get job abroad but depending on the skill and the need of the company. In general how much abroad you think also matters. If you are thinking of Gulf regions then there are good possibilities but if you are thinking of USA then you have less possibilities.

Now if you want to take your career in the next level then you should go for some UG course or Diploma courses to add some value to your career standards. Fields like Data Science are highly valuable for Job purposes. So you have to try a bit as well and have to upgrade your profile.

I hope you got my point. All the very best for your future endeavors!
