The 23-year-old has impressed in America with Atlanta United.
He hopes that English youngsters like himself who are not getting game time in the Premier League can make the move abroad.
Walkes said, per The Mirror: "It was something totally different, I had to leave my family, my comfort zone and it was such a big change.
"I realised I couldn't sit and play reserve or under-23s football anymore. I was sitting in the dressing room one day, Mauricio Pochettino came over and asked me how I felt about the move.
"Pochettino said he knew the coaching staff and said I'd get more minutes and, after speaking to my family, it was definitely something I had to do.
"I'd always recommend coming here rather than dropping down the leagues in England.
"Some guys have been at academies since they were eight years old and to leave at 21 or 22, it's a big wrench, but it's definitely worth leaving your comfort zone.
"I'm a family man, my family mean the world to me. Stepping away was always hard. But you have to realise there's opportunities elsewhere, be brave and take it full steam ahead.
"I met my girlfriend while I was there, we've got a little one and that was a plus side and I've got my own little family now to keep me focused and that's always important."
He added: "I think you'll only see MLS get better and better. A lot of people's opinions have changed of late. The rate the league is going at, you'll only see it get better.
"Younger players are coming here. It's not a place if you're older and just somewhere to see our the last two or three years of your career. It's way beyond that stage.
"I wanted to be a part of it. I wanted to try something different."
