Prince Harry has turned his back on royal life to live a "more peaceful" one with Meghan Markle. After announcing their withdrawal as senior royals earlier this year the Duke and Duchess of Sussex packed their bags and moved to the U.S. with son Archie.

However, Harry may be forced to separate from Meghan Markle - the duke may have to return to the U.K. because of visa issues.

"I think Prince Harry might come back. Harry will need to because of his visa; he cannot stay there indefinitely. There is the issue of citizenship and there are a lot of tax implications but he might very well come back. I hope Harry does because of his grandparents, his father and even William - although they are not pals at the moment," royal commentator and author Angela Levin said on talkRADIO.

Levin said she doesn't think Markle and Archie will return with him. She said the duchess has shown her life as a royal was "horrid" and "ghastly in every way."

Meanwhile, since Harry and Markle moved to Los Angeles there has been speculation the duke will apply for U.S. citizenship. But a source told E! News that the prince is not applying for a Green Card or dual citizenship.

After their relocation Harry and Markle were expected to launch their new brand in the U.S. In April the couple announced the name of their new foundation, Archewell.

Harry and Markle said they were inspired by the word "Arche," which is Greek for "source of action" and is also the name of their son. Archewell is expected out later this year but they have been working on it for months.

Harry and Markle were also said to be trying their luck in the entertainment industry. They have said they want to be "financially independent" - so they need to find sources of income to pay for their lavish lifestyle.
