All you got to do is:
1. Pick a company.
2. Look up where their employees work on LinkedIn.
Observe companies like Texas Instruments, Qualcomm, Applied Materials, etc. 30% - 40% of their Engineering workforce lives in India, China, Philippines, Malaysia, etc.
Don’t take my word for it, literally visit the companies’ LinkedIns.
Bonus:
Click on American employees at these companies and see what they look like.
