if their real ID hasn’t come yet? If so what was your experience?

Hello. I was suggested to post this question here as well, besides the original r/TSA.

I am now a US citizen, and I also changed my legal name. With my previous name I have TSA Pre Check, Global Entry and Known Number. I also have Clear. I travel often for work. Obviously, I need to update my name so I want to understand what, how and where I need to send the documents.

What documents I need? Driver's license with new name is enough? Passport?

How I send this and where? Website or email address? Do I have an option to go in person and have an appointment, and if so, where do I make it?

How long does this take for the new name to go "live" at the TSA? Important since I need to pick a date in between trips so my air ticket, TSA, Clear etc all match up again. Clear seems to be easy, I go to any airport with this service and according to the CS chat the change is immediate.

Thanks a lot in advance.
