all please.

I want to take a course between these three skills.

UX/UI design
Cyber security
Project management
(Website developer -full stack This one is a bit technical)


Please, between this four, I want to know the best and the one that has the highest career prospects and the one I can use to relocate abroad if I want to use it to relocate and the one that has a massive job opportunities and good salaries.


Please your responses are needed. These are the careers


Any advice on an IT skill would be appreciated as well

Look for introductory courses in the mentioned skills, go through them and choose.

For UI/UX google the Accenture user experience course (free)

For cyber security try cybrary.io

You can check Coursera, Udacity, Udemy etc for the last two.

Lastly, it would be easier if you find a career path you have a passion for and develop skills in it.

karlxavier I'll highly suggest Cyber Security or Full-Stack Web Development.
Why?
CyberSec has a really high job prospect, the stats shows a lot of unfilled positions. With cybersec skills you can relocate abroad and source for jobs, and if fortunate you can get a sponsored job. CyberSec has massive job opportunities and pays well.
Fullstack Web Dev is also profitable too.
If you go the CyberSec route, please try to get a SANS(GIAC) certification with the exception of Pentration Testing, for that OSCP it is.

These certs are quite expensive, so once you have funds try get them, it makes difference. In addition, as you are developing your hard(technical) skills also develop your soft skills because your soft skill is equally or more important than just hard skills.
In 2022 sometimes soft skills is the difference between getting that job or not, soft skills is also the difference between someone earning Xdollars and another person earning Ydollars.
Jobberman has a soft skill training, do your research on that.
