土土得问：online bank大家怎么把钱转过去？寄支票？安全吗？在ｌｏｃａｌ的银行操作觉得比较安全，网上银行，老觉得不放心

same question here. I guess you can transfer money to your online bank from your local bank.

But what if you need cash from your online bank? Also withdraw from local ones? will extra fee be charged? thanks

usually you can establish a link between your local check account and the online bank. transfer money between them are usually free.

As long as it's fdic insured, there's nothing to worry about.
