Aljaz Bedene believes already representing Slovenia in the Davis Cup does not dilute his attempts to represent Great Britain.
Slovenian-born Bedene will qualify to play for Britain in February if his passport application is approved, after living in the United Kingdom since March 2008.
The 24-year-old said he sees "nothing wrong" with his bid to switch nationalities.
Bedene crashed out of the Queen's Club Aegon Championships courtesy of a first-round defeat to Paul-Henri Mathieu on Monday, but admitted he hopes to convince future team-mates of his determination to represent Britain.
Bedene has represented Slovenia three times in Davis Cup action - but claims the 'dead rubbers' mean he has not taken full part in the competition.
"I really love living here, I love British people: I feel like I'm at home," he told the BBC.
"I feel I have been living here longer than six years, I have felt British already for a few years."
British number two Dan Evans reacted with dismay to news last month Bedene would seek to switch nationalities, tweeting: "So a guy is becoming British who has already played for his country. Doesn't quite sound right to me!"
Bedene still faces a battle to secure a British passport in time for the next Davis Cup action in March next year, and he admitted he must still persuade team members he deserves to fight for selection.
"There were a few negative comments about that, but I just played dead rubbers," Bedene said of his previous appearances for Slovenia.
"I never actually played a live rubber so I wasn't really fighting for a country in the way I wanted to. So I want to play for Great Britain in a live rubber if I get a chance and I think there's nothing wrong with that."
Admitting he is yet to start the charm offensive with the likes of Andy Murray, Bedene said: "Not with the ones at the top. Not Andy yet. But I've spoken to my friends - like David Rice, Ed Corrie - they seem keen, although I don't know what they're thinking when they are not with me.
"But I think in the end they will accept me. I see myself as a British player, and I hope they recognise that as well."
