XCM transport fees are currently limited to using DOT (or some other single asset configured by the runtime).

There is work planned under [Asset Transactor on Asset Hubs not Working With Sufficient Assets · Issue #3958 · paritytech/polkadot-sdk · GitHub](https://github.com/paritytech/polkadot-sdk/issues/3958) to give the ability to hook in `asset-conversion` for XCM transport fees, and thus be able to just-in-time swap whatever for DOT, thus completely supporting “fees in USDT” on Asset Hub.

Exploring options for other chains here: [Asset Hub Brainstorming Session - Call Notes and Discussion Continuation - #2 by acatangiu](https://forum.polkadot.network/t/asset-hub-brainstorming-session-call-notes-and-discussion-continuation/7260/2)
