What is the salary of UGNX mold designer abroad?

I have a friend who is engaged in numerical control programming in the United States and is also a mold factory with an annual salary of $200,000. If you want to go, you must apply for immigration approval first. This is the biggest difficulty. English can be said to be necessary or not. Immigrants must learn basic English. As for industry majors, English is not tested, but many foreign countries do not recognize domestic skill certificates. And must hold the corresponding skill certificate, and hold the relevant certificate when working in a technical type of work. So, you need to know a lot of industry-related English, otherwise, you won't understand the test questions.
