I think you can get this data from https://www.foreignlaborcert.doleta.gov/performancedata.cfm https://www.foreignlaborcert.doleta.gov/performancedata.cfm with the caveats noted in https://en.wikipedia.org/wiki/Labor_Condition_Application#Data_released_by_the_Department_of_Labor https://en.wikipedia.org/wiki/Labor_Condition_Application#Da... - this is data from the Department of Labor about "Labor Condition Applications" for H-1Bs. Most but not all of these turn into H-1B petitions, and some but not all of these are granted. There doesn't appear to be a public dataset of salaries of active H-1B visas. I'm looking at the data, I'll reply once I remember how to `import xlsxreader`.
