Is Gate.io not allowed in the US?

Excuse me, could you please clarify if Gate.io is indeed not permitted to operate within the United States? I've been hearing conflicting information and I'm trying to understand the current regulatory stance on cryptocurrency exchanges like Gate.io in the country. Are there any specific regulations or restrictions in place that prohibit its services from being accessed by American citizens or residents? Thank you for your time and assistance in clarifying this matter.
