IRCC officials had written to Partey to express concerns about whether his application had met the requirement to "answer truthfully" and referenced legislation covering misrepresentation which could impact a visa.
The court also noted that under immigration rules "having reasonable grounds to believe that an offence has been committed is sufficient" and a conviction is not required "to find the applicant inadmissible".
In a statement, US customs and border protection (CBP) said: "The US is aware of the pending court case for Mr Partey. However, at this time, he has not been convicted of a crime and was admitted to the United States after being issued a visa.
"Admissibility determinations are made on a case-by-case basis using law enforcement, national security, and immigration information available at the time of inspection. CBP defers to Canada for questions on his denial of entry."
Partey, now with Spanish side Villarreal, has played more than 50 times for Ghana, having made his debut in June 2016.
Before the tournament, head coach Carlos Queiroz said he had no qualms over selecting Partey.
Asked about the issue again on Tuesday, he said: "My business is to play with the cards that I have in front of me.
"We are waiting for a decision. When the decision [arrives], we are ready."
Ghana play England in Boston on 23 June and Croatia in Philadelphia on 27 June.
They could return to Canada in the last 32 if they finish as runners-up in Group L.
