If you want to have your interview right away the thing to do is to check the calendar often, they open last minutes interviews and you have to be ready to leave your place!
I was refreshing the page every 15 minutes and at 12.40pm i saw a spot for the 2pm interview, i took all the documents and i jumped in my car! Google told me 55 minutes drive + border wait (nexus offices in Washington States are 10 kms away from the border) and at 1.45 pm i was on the parking lot lol
When i pre-register with the front lady, i wasn't even on the list but because i had the letter + number confirmation, i was good to go! And she told me, i always told people to do that but nobody trust me, and thank you, you are the proof that it's working !!
So now, guys you know what to do if you don't want to wait 1.5-3 month for an interview! (it's the time frame here in Vancouver or Whashington State)
