How much does it cost to transfer USDT?

I'm interested in making a USDT transfer, but I'm not sure how much it will cost. Could you please provide me with some information about the transfer fees for USDT? I'm also curious about whether there are any hidden costs or additional charges that I should be aware of. Additionally, does the cost of transfer vary depending on the amount of USDT being transferred or the destination of the transfer? Thank you for your help.
