There are reports that USCIS and other immigration agencies are checking LinkedIn (as well as other social media sites) to check consistency with employment-based applications, like Forms I-20 and H-1Bs. Therefore, if a Form I-20 lists specific authorized employment but LinkedIn exaggerates that employment (ex. part-time internship represented on LinkedIn as full-time regular employment), there are reports that USCIS is denying OPT applications.
