Sir, I think it is possible as he is now living in the US and Binance provides that opportunity for the US residence. According to Binance US, it supports USDT on the Tron network. It does not require KYC for a person who is living in the US, but there is a small limitation there like if you have no KYC you can trade just a few thousand dollars which is $10,000 I think per day. However, Binance.US is not working in all states of the US, so we don't know in which state of the US he living. According to me, binanace.US is the best exchange for those who don't want KYC. If you are not sure plz DYOR.
