Can I send USDT to any network?

I'm a bit confused about the intricacies of cryptocurrency transactions. Could you please clarify for me? Is it possible to send USDT, the tether stablecoin, to any network without restrictions? I've heard that different cryptocurrencies have their own specific blockchains or networks, and I'm not sure if USDT follows the same rules. Could sending USDT to an unsupported network lead to any issues or losses? I'd really appreciate your expert advice on this matter.
