Let me tell u truth. Getting into good cpa network is very difficult specially when you are noob. Now being just American also don't help much nowadays. You should try your luck in affiliate marketing learn things and then try in CPA. Don't think just getting into cpa network will make millions. This is kind of bubble most newbies live in after hearing hyped up cpa millionaires stories.
If you know little about how to get traffic or know about Internet Marketing then you are welcome to our network. CPABounty.com
I got accepted into Max Bounty and I'm relatively new to the game. Just be honest, if you don't have CPA experience then say that, but you should at least have a website to show them - that's all I really had. Also, make sure to call back immediately if you miss the call. I was asleep when they called and I called them back and got accepted. When I checked my inbox I had a message saying "sorry, your application was rejected" and another above it saying "your accepted!" that was sent right after I got off the phone.
Many networks are not "hard" to get into, but as BacklinkBen said, you have to be honest with what your doing. You don't necessarily need a website in order to market and many networks including ours will still accept you depending on what your traffic methods are. Have your plans and goals down.
