Planning to do an Apporama but have some questions before applying.

Will apply for a Chase card and Citi card which will replace a Ritz card and Citi Executive.

My questions is...

Been about a year since my last application and would like to get an instant approval if possible.

1. Should I close my the cards without moving my credit line and then apply for a better chance? - Chase

2. But for Citi, they said I'm eligible for credit increase without any hard inquiry so should I increase and close or just close it and expect a better chance of being approved for the new application.

I have 4 chase cards (3 personal, 1 business) and 5 citi personal cards.
