Meghan Markle loves traveling, but she may give up her favorite travel item.

According to Kara Godfrey, a journalist for Express, the Duchess of Sussex revealed earlier that her favorite travel essential was her US passport. However, she may give this up as she is getting a UK citizenship and due to tax information.

"I can also say she intends to become a UK citizen and will go through the process of that, which some of you may know takes a number of years," Prince Harry's communication's secretary, Jason Knauf said.

Markle can be a dual citizen and hold on to her US passport. This will allow the Duke and Duchess of Sussex to live in the U.S. and have their children as U.S. citizens, too. However, this choice is not wise to do so for a member of the royal family. The US rules regarding tax information will require Markle to submit her finances which is not preferable to the members of the Firm who are "notoriously private about their income."

Markle, Prince Harry, Kate Middleton and Prince William need their passport and visa whenever they travel. The only member of the royal family who is exempted is the Queen.

Instead of going through passport control, the monarch will only need to answer a few questions to prove her identity. Among the questions asked are her name, age, address, place of birth and nationality. It doesn't make sense for Queen Elizabeth II to own a passport as it was issued in her name.

"Her Britannic Majesty's Secretary of State requests and requires in the name of Her Majesty all those whom it may concern to allow the bearer to pass freely without let or hindrance and to afford the bearer such assistance and protection as may be necessary," the first page of the passport read.

In related news, the Duchess of Sussex and Duchess of Cambridge used a secret item to avoid Marilyn Monroe moments especially when they are on the tarmac. According to the expert, they use fabrics that connect to their body.

"Often they wear body suits and clothes that actually increase static so it’s much hard for something to fly up," Myka Meier, founder of Beaumont Etiquette, told The Sun. "So you have an undergarment that is almost like a body suit that is one tactic that is used."
