One of the biggest things of concern when you apply for Labor Condition Application ( LCA ) or apply for H1B visa in a particular area is the minimum wage or prevailing wage in that area. It is very important and many H1B visa holders or students willing to get a new H1B visa look for this information. You have to make sure you are not working below the minimum or prevailing wage in that geographic location for your particular position. This website for Foreign Labor Certification Data Center maintains the information for prevailing wage and is pretty standard to get a baseline of prevailing wage. The website is reliable as it is built and maintained by the State of Utah under contract with the US Department of Labor, Office of Foreign Labor Certification. Here are screenshots of how to look for prevailing wage.
Just go to the homepage of Foreign Labor Certification Data Center and select the search wizard.
Select the options of All categories , Area or City you live in and Job title you are looking for
Once you are done, finally it shows the wage. It looks something like this : Make sure your LCA is at least above the wage specified here. It is kind of a baseline.
