I've been constantly maxed out on deposits for 8 months or so, they haven't upped it yet. I spoke to a lot of people at Chase who told me that there's no way to up it. I also did a lot of research and didn't find any DP that that's the case. The only way around it was to open multiple accounts each with a $5/15k limit.
I don't know, very interesting. It didn't take me so long and I wasn't maxing it out. I kept getting invites for CPC so maybe that made a difference, but I doubt it, and I think then the whole world was getting invites. Maybe find someone who is CPC and open something joint with them.
