I went for an increase to $25k (scared to request a 3x) but was asked for income verification. I lowered to $20K and asked again. Last time, I asked for $15k and was approved.
Scores still mid 700's.
For those of you who had been presented with an income verification from amex, do you just go along with it? the income i put is right ($180k) but i dunno if it'll present problems for going through with it. I just back out and shoot for a lower limit that will give me instant approval. This also happened with my last cli from amex back in september.
Congratulations on your CLI!
