He would have had to surrender his US citizenship altogether to be eligible through citizenship alone and even then it would be subject to IIHF approval.
IIHF Statutes & Bylaws, bylaw 4.2.:
"An Eligible Player who has two legal citizenships or more, or has changed citizenship or has acquired or surrendered a citizenship and wants to participate for the first time in an IIHF Championship described in Bylaw 11-13, a Men’s Olympic competition or a Men’s Olympic Qualification competition for their Country of choice must: a) Prove that they have (i) participated in the League Competitions within their Country of choice on a consistent basis, over at least sixteen (16) consecutive months (480 days) and during two (2) hockey seasons after their 10th birthday (ii) resided in their Country of choice during that period and (iii) neither transferred to another Country nor played ice hockey for a team registered or located within any other Country during that period"
Thanks for the clarification. I get it now - for players with dual citizenship, there are extra requirements, including living and playing in the chosen country for a certain period, and possibly giving up the citizenship of the other country.
According to IIHF rules, for Josh Doan to play for Canada, he would need to meet these conditions:
1. He must prove that he played in competitions in Canada consistently for at least 16 months and during two hockey seasons after his 10th birthday.
2. He has to have lived in Canada during that time.
3. He can't have played for teams registered in other countries or be registered with other countries during that period.
If Josh meets these conditions, he should be eligible to play for Canada, even if he has US citizenship. However, if he hasn't met these requirements, he might have to renounce his US citizenship to be eligible to play for Canada. Am I right?
