You keep asking it and you keep getting the same answer because you're not supplying any constraints. It's quite disingenuous that you don't seem to be doing any of the research yourself. This kind of thing is not a secret; why would it be? Countries that have an immigration policy more inclusive than 'nobody ever' are going to make their requirements well-known to attract immigration of skilled talent. (Or, if they lack unskilled talent, visas may be available in that category instead.)
That's really the most vague wording of that question you've tried yet, and I answered it fully in another one of your comments, but just for you here's the UK's details.
Let's take a typical case. A skilled worker defined is by the UK in the folowing document:
The list of occupations with exceptionally desirable skills is given:
On page 6, you'll find:
2136 Programmers and software development professionals:
The following jobs in visual effects and 2d/3d computer animation for the film, television or video games sectors:
- software developer
- shader writer
- games designer
The following jobs in the electronics systems industry:
- driver developer
- embedded communications engineer
Eligibility is described in this document:
- certificate of sponsorship reference number
- an ‘appropriate’ salary
- meet the English requirement
- £900 in savings (£945 from 1 July) - this is to prove you can support yourself and you must have had this in your bank account for 90 days before you apply. You don’t need to have £900 in savings (£945 from 1 July) if your sponsor is fully approved (‘A-rated) and they have stated on your certificate of sponsorship that you won’t claim benefits during your stay.
If you are a graduate with a credible business idea, you would look here instead:
There are other pages for industry captains, exemplar scientists, artists, sportspeople and so on.
So, for the last time: Find a list of countries that meet your own personal requirements (common language, firstly). Discover their requirements by searching online, or telephone them (information can be found from your local library). If you don't have a library, or a phone, or a workplace, or an internet connection, you are poorly equipped to attempt this. Contact their immigration offices to get a definite list with some solid crunchy numbers and facts for you to use as milestones for your application. Determine what businesses are located in your target country that would be hiring peoples with your (verifiable, i.e. certificated) skill set. You will have to search online, or in electronic or paper trade directories/journals, or speak to acquaintances, friends or colleagues. Contact the necessary businesses for information, and eventually interviews, this may cost money; get a part time job. No, this won't be easy if you're too young to work at an adult level, but if you're too young to work you probably don't have the certifications either (there will possibly be age restrictions for minors too) so it's a non-issue. If and when you are conditionally hired and sponsored (if required) by the company in the target country, organise necessary paperwork, double check all prerequisites (housing, medical registration, for example), and execute the plan.
