I waited until I had my Amex Green card approved with ITIN for 15months and by that stage had my GT Amex cards around 2 years. No checking account with Chase and approved with 17.5K CL after identity verification.To those of you who have Chase cards, did you all wait until your US credit history is at least one years old, and i assume most of you did not have a Chase checking account when you applied for your first Chase card ?
