expect to see more of this. We are learning about this in class. Some US employees will be paid more to make the transition to another country to train people there and work with them. It may be for a few years or so. Then they would come back to the US for a while, and do it again. A work visa or passport only allows a temporary visit in a country, but then it depends on the country's laws. You also have to learn the culture, native language, and government and laws. Don't do any moonlighting, only work for the company who sent you. Some people are making as much as $300,000USD a year to travel to other countries and help them set up business there.
My instructor has a company he owns that does that and more, also teaches US businesses to make improvements, avoid fraud, and manage better. They can spot fraud in a business and teach them how to avoid it in the future. Like someone embezziling money or using funds for personal needs. They can also teach organizations in other countries how to have quality control, manage better, etc.
Indian organizations vary on qaulity, some have it and some don't.
