Do I have to have a round-trip ticket to visit relatives in the United States?

Of course, don't you want to go back to China without buying a round-trip ticket? Your B 1 visa is valid, but when you enter the country (the US Immigration Bureau still has the advantage of not allowing you to enter the country), so under reasonable circumstances, a round-trip air ticket is necessary to prevent the Immigration Bureau from suspecting you and not allowing you to enter the country.

Brother, it's up to you whether you want to go or not. Don't save the money for the return ticket, or I promise you won't enter the United States and be repatriated by the immigration officer.

It is possible and necessary to go to new york first, because there is no direct flight to Texas in China, so we have to change planes. It is reasonable to go to new york first.
