They might ask to make fd for higher limit. During application process my rm said they approving my infinia but with 4.5l limit, make 3l fd to get more limit upto 10l. To show having higher relationship with bank. In saving account was 10L. Fd not linked to cc, can close anytime.I have gone ahead because this is the only good card missing in my collection
But Not sure whether it was CC department requirement or rm completing his target.
