Wilson is yet to make a competitive debut for Giovanni Trapattoni's side despite being selected for several squads.
However, the County Antrim-born 24-year-old, whose cause may not have been helped by a series of withdrawals at a time when the Italian was less than happy with the failure of several players to report for duty, insists he has no regrets about declaring his allegiance to the Republic.
Wilson told the club's official website: "I have always seen myself as a Republic of Ireland player.
"I supported them when I was growing up and if I have to continue to bide my time and wait for my chance to come along, I am happy to do that.
"The players and the gaffer have done a great job there, so I can't complain about it really.
"I would love to play for them, though, one day and I have made that clear before a number of times. Hopefully, my time will come in the future.
"I would love to try to be part of the squad for the European finals, but if that doesn't happen, then I will keep working hard here at Stoke and try to earn a spot in the Ireland team."
New Northern Ireland boss Michael O'Neill is aware of Wilson's eligibility, but the player insists there is no turning back.
He said: "There is no way I would switch to Northern Ireland, though, now.
"I made the decision a few years ago without having my head turned by anybody, and I am sticking by that. It is something I am comfortable with."
