I am opening a bank account? Which bank is better and howe should i choose my bank ?

Well, I recommend a national chain (US Bank, Wells Fargo, Bank of America, etc.) in case you move out of your region--I had my bank account at a local credit union and had to get a new one when I moved away! But really, it doesn't matter a lot. Interest rates are all about the same. Just look up ones near your home on the internet and see if any of them have features that you have to have. But honestly--they're all pretty much similar.
