Denver spokesman Nina Muniz told the Denver Rocky Mountain News that a conviction is grounds for deportation, but Roy would not be forced out of the country just based on the conviction alone.
The U.S. Immigration and Naturalization Service determines deportation on a case-by-case basis.
Roy is currently living in Colorado under a P-1 work visa used by professional athletes and entertainers.

Roy was arrested Sunday after an argument with his wife, Michele Piuze, resulted in two broken doors at the couple's Colorado home.
Police arrived at Roy's residence after receiving a "911 hangup call." According to The Denver Post, the legendary netminder was taken away in handcuffs and spent six hours in jail before being released.
Later, Roy's wife explained she'd made the call because she was afraid of what her husband would do as they argued about in-laws.
Roy has been charged with misdemeanour criminal mischief. If convicted, he faces a maximum of a year in jail and a $1,000 fine.
Roy, accompanied in court Monday by his parents, sister and brother, admitted to damaging the doors after his wife called police and hung up without speaking.
The initial hearing was postponed until Nov. 7. Roy remained free on $750 bail.
But the judge issued a restraining order that prohibits Roy from consuming alcohol or using illegal drugs. Roy is allowed to return to the family home. He is also permitted to travel to out-of-state games with the Avalanche.
After attending the hearing, Roy participated in a practice with his Colorado teammates. Later, Roy told the media his lawyer had advised him not to comment on the arrest or hearing. However, Roy did admit the situation was weighing heavily on his mind.
"Obviously, this is creating a distraction, and my wish is that this distraction will be over soon," he said. "I am thankful for the support I am getting from my family and every one of my teammates."
Roy also asked that the public respect his family's privacy.
Members of the Colorado Avalanche have offered Roy their support.
"We've always stuck together and we'll stick by Patrick," defenceman Ray Bourque said. "We know he is a quality person and a great family man."
Defenceman Aaron Miller said, "Until we find out exactly what's going on, we're not going to let it bother us or distract us. I think I speak for the whole team that we're behind Patty 100 per cent."
Last week, Roy won his 448th regular season game, surpassing Terry Sawchuk and becoming the NHL's winningest regular-season goalie.
