Welshman insists he's too old to make future switch.
The one-club man has enjoyed a remarkable spell at Old Trafford, and is currently the club's record appearance holder after playing 838 times since making his first team debut in 1991.
A number of stars - such as ex-team-mate David Beckham and impending New York Red Bulls signing Thierry Henry - have decided to close out their playing days in Major League Soccer, but the most decorated player in English football history will not be following suit.
Speaking to USA Today, Giggs stated his belief that, at 36, he would be too old to make an impression in America when his United contract finishes at the end of next season.
"Being in America you have a great lifestyle, good for raising a family," Giggs said.
"The play is getting better. I still have a year left with Manchester United. After that maybe, maybe I will be too old."
United traveled to Chicago on Monday for a training camp before games against Celtic,
Philadelphia Union, Kansas City Wizards, the MLS All-Stars and Chivas Guadalajara.
Giggs believed the opposition will provide the perfect platform for a successful campaign ahead.
He said: "MLS has grown and the success of the USA in the World Cup can only have helped football.
"We want to get our fitness. It is a good opportunity to get our rhythm against good competition."
