You met the best girl over the internet she lives in the US you live in Australia but would do anything to be with her If you get married over there are you able to stay?

Answer 1

The long answer is eventually yes, as long as you follow proper procedure. The short answer is that if you come into the US on a visitor visa, get married, you will still have to go back to Australia and have her file for a spouse visa. If, instead, she applies for a fiance visa then you could come to the US (after you get the visa), get married, and stay - but you have to file further paperwork after you are married (must be within 90 days) for an adjustment of status. This will give you a 2 year green card. At the end of the two years, if your still married, you can apply for an unconditional green card (good for 10 years and is renewable).
