H1B visas in the US are work visas. An employer says they can't find enough citizens to fill their jobs and the government issues them some H1B visas so they can hire Indians, Chinese or other foreigners.
LCAs are the application for H1Bs submitted to the Dept of Labor by the company. The visa sponsors(employers) are sorted by the number of Labor Condition Application(LCA) submitted. The number includes new, renew and transfer of LCA.
This is the other end of the wage scale, some people make fun of poor people who say "they took er jobs". Well this is middle class, often upper middle class, workers saying the same thing about H1B workers, a lot of these jobs are for over $100K a year. Even if H1B workers don't replace you directly, many will tell you that they keep wages artificially low by oftentimes working for less than a citizen would.
I've never been replaced by an H1B worker but after I left a job management replaced me with an H1B worker.
