@mcd1231 @IRonMaN @Just-Lisa-Now- @sjrcpa I think I may have just found the answer. On a website called dockwalk.com. "foreign flagged vessel employed by foreign entity might not be required to pay social security and Medicare tax." You can go on this website yourself, but I would use  smartphone to do it, just in case of any viruses or something like that. But website does look legitimate . Hope this helps. Just my opinion
