Wilson is yet to make a competitive debut for Giovanni Trapattoni's side despite being selected for several squads.
He said: "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."
