First Double-check the network to make sure you selected the Sui Network when withdrawing from Binance. USDT exists on multiple chains (Ethereum, Tron, BNB, etc.), and if you used the wrong network (like ERC-20 instead of Sui), your funds might be stuck. You can verify the transaction on-chain via https://suiscan.xyz/ and paste the wallet address you sent the USDT to. See if the transaction shows up there.

Always make sure the token and the network match 100% before making any transfers.

Unfortunately not, transactions once done are irreversible.
