Serious Question. Finding a job related to Solidworks as a foreigner.

Hey guys. Im searching for a real life, down to earth answer related to my question.
Feel free to dive in, provide any sort of hard-core, down-to-earth advice or anything necessary.

Anyways, Im currently working as a software tester in South Korea (South Korean).
While i do have some understanding in programming, my actual interest is in 3D images.
As a side project, ive been working on SolidWorks, and sooner or later will try as hard to master it.

I do not have an engineering degree, do not have a degree in design, but 3D design related to the fields above is very much interesting.

So my question is,
1. What are the requirements for an entry level position related to 3D desgin?
2. Are companies located in the U.S. or in Europe interested in hiring a foreigner (visa sponsoring and everything)
3. What additional knowledge do i have?

Thanks guys. Please help.
