I've been reading this forums for a long time, but this is my first post, I'll give my whole story as short as possible
I moved to the US almost 2 years ago, in my home country I had an impressive perfect credit record, then the opportunity to move came and because what it meant to move to the US for my professional career I accepted.
As soon as I got my SSN, I was able to move out of the hotel room and get me a house, to start it made sense to rent, in the near future buy (if everything goes as planned and I move from a work visa to a green card), so I rented, first hard pull, I needed a car and return the rented car, to pick it up I needed my SSN and credit check, second hard pull, open a bank account, cell phone, utilities, etc etc... at the end, I ended up with tons of hard pulls in my report, just to settle in the country.
I started applying for a couple cards, all denied, credit for me has always been part of my life since I was in college and also I know I need some credit history to acomplish many of the things I want, so a friend told me about this forum and also gave me some advice, and this what I did after reading here.
Step 1.- Get a secured card with Cap1, $350 USD deposit, AF and high APR, got the card, started using it to pay utility bills
Step 2 - Wait a few months, PIF everything I charged
Step 3 - Cap1 pre-approved me for a cash back rewards card (2% groceries and gas, 1% everything else), high APR and an AF, but unsecured for $ 500 USD, got enrolled in the credit steps, use it for gas and groceries only, PIF (sometimes 2 or 3 times in a month)
Step 4 - wait a few months,
Step 5 - Got approved for an Orchard Bank Card with $300 USD, HIGH AF and REALLY HIGH APR, got it, but hardly use it, just wanted to increase my available credit and build some history
between step 5 and 6 I decided to change banks, Wachovia/Wells Fargo was not helping me at all and just charging me fees for everything, so I moved to BofA
Step 6 - Applied for a World Rewards Card with BofA, got approved with a $1,000 USD, no AF but high APR
All the cards got me hard pulls, so now my report has 14 hard pulls, but a credit score of 715, I PIF every month anything I charged to the cards and try to keep my utilization below 10%, I'm never late with my bills or cards.
After 6 months, Cap1 increases my line on the secured card from 350 to 450 USD, didn't ask for a deposit to cover those 100 USD, and also jumped the other card from 500 to 750 USD.
I got a letter from FNBO saying I was pre-approved for a Discover card with them, so I applied and got approved (I wasn't expecting this), when I got the card, it had a $5,000 USD limit, no AF and low APR, the same day I got approved with FNBO, BofA did a CLI to my World Rewards card and bumped me from 1K to $2,500 USD.
The same day I received the card from FNBO, I went online to activate it and setup the payment method, alerts, etc and found out that they bumped me 5K to $10,500 USD due my excellent credit 
So this where I am right now, my plans are (any advise is well taken), wait for at least 1 year before I apply for anything else, let the cards and credit lines mature and age a bit, cancel the Orchard card before the AF is due, as it is too high for a 300 USD card, keep the secured card with Cap1 for one more year at least, don't ask for any CLI's.
Any other suggestions??? and btw, thanks for everything, I followed many recommendations made to other members
