Doubtful that he’s “frequenting” there given how he left the country. When the FSB (Russian FBI) demanded he comply with the laws and provide the decryption keys he had his lawyers send a prank letter to the head of the FSB with two physical keys (as in, the actual keys you open your door with) attached to it as a sign of “compliance”. Try that in the US and see if you can “frequent” the country after that.
