Secretary of State Marco Rubio recently announced that the United States would pause the issuance of worker visas for commercial truck drivers, citing concerns about road safety and the livelihoods of American drivers. The move has been praised by some industry groups that have long warned about the misuse of commercial driver’s licenses issued to foreign nationals.

Still, the decision by President Donald Trump‘s administration comes at a time when the United States already faces a truck driver shortage. Nearly nine months into Trump’s second, nonconsecutive term, the truck driver visa freeze also raises concerns that it could create new strains on supply chains, affecting the economy as a whole.
