What technologies are relevant for immigration to the West?

Question

IT education

Hey toaster.
I am almost 20 years old, a first-year student (Mathematics and Computer Science on a budgetary basis. Profile: Mathematical Methods in Economics and Finance ). For a couple of months I studied the basics of Java in "Java for Dummies" and "thinking in Java". After that, about half a year ago, I started typesetting. I mastered rubber, adaptive, preprocessors, git, bem, I can do primitive things in JS, I picked a little WP. Passed courses on layout from the academy. Not freelancing. I thought about leaving.
The goal is to find a job in the West in the future.
I understand that green programmers are not needed there, and you need to be a first-class specialist to get an invitation.
Questions:
1. Which direction is more promising for immigration to the West?
Java - business, science, trading, big data, embedded systems, etc. At this stage, it’s hard for me to decide, because I haven’t worked yet, but the variety of areas attracts + this is my first EP. The desire to study was and is. I read that competent Java, Python, C ++ programmers with big data, machine learning, cloud computing skills are needed there and will be needed in the future.
Web - an opportunity to start freelancing very soon. The web is interesting, but are web programmers needed in the west? I read that the need is small. Is it so?
2. Education. The crust can help with finding the right tractor + knowledge of mathematics. The question is different.
Is it worth it to transfer to a programming specialty (there is less cursing)? Or still get some analytics skills and more knowledge in mathematics? Or maybe even transfer to part-time and look for a job?
Thanks in advance to everyone who will read this and critique and/or give advice. Now this is very important to me.

Answer 1

If your university has a good foundation in mathematics, stay on mathematical methods and engage in projects with data, study java / python / c ++ in parallel. Obviously, science-intensive areas are more promising. Yes, you will not earn money right away, but the question is about the prospect of moving.
The web has a lot of its own specialists, on the ground, there is no need to "import" them (only in very narrow topics of the web).
Employment in outsourcing generally does not guarantee a chance for the team to move.

Answer 2

Transfer to part-time and look for an internship/outsourcing job.
If there are large companies with an internship (internship) in your city, find out everything right there. You can get a job there as an intern, and if the project is foreign, maybe in the future you will move through the same company, even remaining within the framework of the project.

Answer 3

Learn Python (if possible, also R) and do Machine Learning. Deep knowledge in mathematics will greatly help in this matter, and such specialists are needed "in the West."
