Amazon Card is little difficult to get if you have no income. You can neither get add on cards neither you can get a secured one. If possible, only if possible open an Insta Save account with ICICI after contacting them they may give you pre approved offer. This happened with me, I got the offer just by maintaining 20k on my account, it's not my salary a/c then also they gave me... You can get Platinum/Coral by putting an FD. + ICICI cards are easy to get, you just need a minimum income (take home [after tax] salary) of 12,000 rs. So you can get one immediately after your first salary slip.
Good luck!
You can also try OneCard, they give you 110% credit limit of ur FD.. IDFC First Bank's First Wow! Is the best card against fixed deposit. Not only you get a good reward rate, it comes with Visa Infinite, 100% Cash Withdrawal of your FD and also IDFC offers. No annual or joining fee, you also earn interest on FD
