Its not as simple as that. No company would let you pay for your own flights because it reflect badly on them and how they treat their talent, at the same time they most definitely will be reluctant to fly you from abroad to interview. Hiring is not so cut and dry, although you may have the best technical abilities they may reject you simply because of bad cultural fit.

devbootcamp is clearly not an option for you, i suggest you take spoom's advice and open source a project you can be proud of in Rails. Then maybe attend some conferences in the US, and try and network to seek jobs. I believe you can get a B1 visa to attend conferences and you should be legally allowed to interview, although IANAL so double check.
