Meghan Markle is making final preparations to be a UK citizen ahead of her wedding to Prince Harry. She was seen back in the states on Thursday to finalize her UK visa.

UK Citizenship

A photo of what appears to be the former Suits star exiting O'Hare International Airport in Chicago has made the rounds online. Markle was wearing all black and a White Sox cap when she was photographed riding down the escalator with the Chicago police providing physical security. According to a source, the soon-to-be-princess landed at the airport at 11:30 a.m.

Apparently, Markle is back in the United States to finalize her UK citizenship ahead of her wedding to Prince Harry on May 19. Eyewitnesses revealed that Harry's fiancée tried her best to appear incognito by pairing her cap with dark shades.

However, having a security detail only attracts interest. Sources said four bodyguards followed Markle as she entered the VFS Global UK Visa Application Center. Likewise, the office was cleared for her arrival.

Family Visa

According to sources, Markle paid for premium processing so she can get her visa within a few days. This means she spent about $1,500 for the fee. It is likely that she filed for a family visa and applied as a spouse. This visa entails that she confirm her first marriage and her plans to remarry within six months of arriving in the UK. After six months, Kensington Palace confirmed that Markle will apply for permanent citizenship, which could take up to three years to process.

The 36-year-old California native did not take long in processing her UK visa. It only took 10 minutes. The short visit though may have been a memorable experience for the staff. Markle was reportedly friendly toward them while at the office.

Markle only has a short stay back in the United States. She will not be in the country long as she has to return to the UK Sunday evening to be with Prince Harry as they prepare for their royal wedding.

Prince Harry, 33, and Markle are set to wed at Windsor Castle at a more intimate ceremony compared to the former's brother, Prince William. There will be no political guests at the wedding, according to a Kensington Palace representative. Former U.S. President Barack Obama and his wife, former First Lady Michelle Obama, will not be at the nuptials, even though the couple is close friends with the prince.
