Honestly I don’t think there are enough h1bs out there to make that big of an impact in the employment market. There’s a pretty low hard annual cap

Although you can apply every year for several years before you get kicked out if you don’t get it and stem majors get like 4 years of opt, meaning you don’t need a h1b to work for 4 years post graduation. 

I wonder if it’s those people coz there are technically unlimited number of those applicants
