For my P2, citi declined due to “insufficient credit history”. Won’t explain what they want.

my P2 has had all sorts of cards, including gold, plat, vx, etc. has 6 figure salary. never missed pmt, 8 years of credit history. p2's last card opened was 2 months ago.

wtf is citi looking for? calling them doesn't help. Does anyone have any dp from a similar situation?

p1 applied, 5 mins before, and got accepted. p1 opened gold card 2 weeks prior.
