I intend to apply for these 5 cards this week:

i. Chase Freedom
ii. Discover It
iii. Fidelity Investment Rewards
iv. Nusenda platinum cash rewards
v. Capital One Quicksilver Rewards

My income is $120k/yr and my scores are:

Penfed FICO NG 2: 814
DCU (EQ): 759
CK: 799 (TU), 803 (EQ)
CS: 798 (TU)

AAoA: 4yr. Last application: 10/2013

Questions:

1. Is the order of application correct/optimized for odds of approval? I really need the first 3, but perhaps the Fidelity one should be applied AFTER the Quicksilver to maximize BOTH begin approved? Should I swap ii and iv assuming Discover is not as strict as Capital One for Quicksilver while STILL getting approved for both?
2. What are the chances that I will be rejected by any of them because I am not a U.S. Citizen?
3. What are the chances that I will be rejected by any of them because I will be applying for all of them within a span of few minutes on same day?
4. How is recon for these cards? Which ones are very picky (Won't be applying for another Chase card in 2 years)
5. Would "send $ to a friend" through PayPal be a foolish way of meeting min spend on these credit cards? (Send as friend to room-mate and she withdraws to her bank?)
