Buying in Mexico to use daily in U.S? 🇺🇸

Hello, I'm due for an upgrade since my OnePlus 11 is getting outdated. Unfortunately recently OnePlus backed out of the U.S market which had their phones sold at Best Buy stores. Oppo still isn't available at retail stores in the United States. I was wondering if I can travel to Mexico to buy an Oppo & bring it back to the U.S to use it as my daily phone? Will I have any issues? Oppo still use Google services correct? And I already have T-Mobile as my service which I heard good things about the cellular network service with Oppo phones.

I understand I will be getting comments from people telling me to just buy the global version online, but I really would like to see the Oppo models in stores in person and see how they are. I believe stores like Liverpool and Elektra sell Oppo. I could also use a vacation as well lol. Thank you all.
