Ever since Prince Harry made an appearance at a JP Morgan event in Miami, there are rumors Meghan Markle's husband may work with banking giants. However, a radio talk show host claimed that the Duke of Sussex would encounter a big problem that might stop him from working in the United States.

TalkRADIO host Mike Graham talked about the Sussexes move to North America with the royal expert Ingrid Seward. In the show, the latter assumed that the royal pair might settle in New York or California, per Express.

However, she pointed out that Prince Harry has yet to have a green card. Without it, he couldn't work in the U.S. "They will probably live in New York or California eventually, but then you have all the problems with the residency and the taxes," Seward explained.

She then added that Prince Harry and Meghan Markle have to shell out a huge amount of money to sort things out. Graham then asked Seward if the sixth in line to the throne would be exempted from taxes in the U.S.

"No, and he also doesn't have a green card, so officially he is not allowed to work there," Seward explained. Graham then said that Prince Harry and Meghan Markle would face all kinds of problems in the U.S. It also remains to be seen where they will permanently live and be residents of. Hence, there is a big possibility that their "story will continue to rattle on."

Anyhow, despite the assumption that Prince Harry couldn't work in the U.S., billionaire business leaders reportedly are in a "gold rush" to work with him and his wife, Meghan Markle. Banking insiders told Mirror that the two would be invited to give a talk at the upcoming World Economic Forum in Davos, Switzerland, next year. This event would be the coming together of some of the world's wealthiest and most influential people.

According to the experts, Prince Harry and Meghan Markle could earn up to £1 billion if they manage to network correctly with the delegates and sign a series of corporate deals and roles as brand ambassadors at the event. PR expert Mark Borkowski said that this move was never a surprise at all.

A banking insider added that Prince Harry and Meghan Markle already set a clear path to work with the bank and corporate giants and do philanthropic work with charities. Although the plan seems to work well with their target audience and celebrity set, it may raise the eyebrows of some in the royal circle.
