NCLEX still waiting for ATT letter

Hello everyone!

This is my first post, I graduated last year in the Philippines with a Bachelor's degree. Its been almost a year waiting for my att letter. The Bon ask for so many requirements the latest one was asking for mt RLE TOR and cases, hope they could ask them sooner. If they recieved my requirements how long do you think will i recieved my ATT letter? Will i be able to pick my exam date? For how long?

Hoping for your reply, Thank you!
