I would like to sound a caution, if you are using this data for any kind of salary negotiation.
- LCA for a candidate is filed only once per company as long as he is in the same job role. Factos like getting promoted to Senior X, recent pay-hikes would not get reflected in LCA.
- Wage listed may not include bonus, and other compensation. So dont leave money on the table while negotiating. Crosscheck with glassdoor.
- Companies also go through frequent job title changes, so it is possible you might miss more dataset hidden in other job titles.
- When you are looking for wage related idea, only latest year matters.
- Some people have mentioned earlier that H1B have 10-20% less salary. My personal experience says otherwise. There is always bound to be variation even among non H1B.
Finally
- I am not a lawyer, and none of it are legal or professional advice.
