Guardiola was born in Santpedor, in the Catalan region of Spain, and spent time in his homeland as well as Italy, Qatar and Mexico as a player.
As a manager, the 55-year-old has had spells in Spain, Germany and England – taking charge of Manchester City in 2016.
“It is a problem all around the world,” Guardiola said.
“We treat immigrants or people that come from other countries like they are the ones causing problems for our country. It’s a big problem because the fact I am Catalan and you are British? What influence did we have on where we were born?
“Everyone wants to have a better life, everyone wants to have a better future for themselves and their families. Sometimes the opportunities are where you are born and sometimes it is in the place where you go.
“The colour of your skin or the place where you were born don’t make a difference.”
