Hello,
You surely can go abroad for jobs after MCA. One option will be keeping a track on the companies that accept international employees and directly applying to them. You'll be called for an online interview if you are selected.
The second option is getting a job in an international company in India. There are various such companies like Ericsson. Once you're capable enough, they'll send you abroad for job purposes and it's very common.
You will need to have a good job profile and you'll be able to get your dream job. Even if you start small, you can always improve with job experience. All the best!
