What's the easiest way to legally enter the United States? Love. Fall in love with an American citizen, get married and you're in. Unfortunately, not everyone can rely on romance. Most people have to work their way into the U.S. But to do that, you need to find a job, a company willing to sponsor you and then apply for one of the country's precious H1B visas. With up to 100,000 applications filed each year (that's where the government cuts it off), getting one of the 65,000 H1Bs given out annually is a bit like winning the lottery. The same is true for other highly coveted visas like the L1 work visa, which enable multinational firms to transfer employees and executives to the U.S. For would-be immigrants, such visas can often lead to the ultimate golden ticket: a U.S. green card, 140,000 of which are available each year.
