No, seriously, you can enter the US on a K-1 Fiance(e) visa and then get married. Search the K-1 visa on google, and you will come up with a number of very helpful sites that will walk you through the process.
You only have to get engaged to your sister/brother or marry your cousin IF you plan on living in Appalachia OR plan on voting in a red state.
