Research assistant positions at foreign universities?

Hello everyone,

I will be completing my masters by summer 2027.

My current research interest & experience lies in the area of semiconductor electronics/optoelectronics materials.

I want to do a PhD from abroad, preferably US, but want to gain more research experience before applying by doing projects, assist, learn, contribute and publish under a researcher/professor.

Do Japanese/Taiwanese or European profs take passed-out students as Research Assistant for long-term projects for a year or so?

If anybody has any knowledge or experience of something like this, please share here. It would mean a lot to me.
