Walaikum Asalaam,No no I actually I was thinking to sign up next year not this year of course! I know it's already late.
As a dear one says, it's all about whether or not you have an invite InshaAllah.
Dar El Salam is sold out... You can try asking though.
Just remember that people from the states are starting to leave by Oct 21st InshaAllah (depending on the programs of course).
When's the best time to sign up? Now I hate asking this question because I know there's a time when the whole world will be in rush to apply until you miss your place. Am I wrong?
