U.S. Customs and Border Protection announced on June 15 that effective immediately, it would no longer permit Mexican citizens to cross into the U.S. on temporary visas to sell their blood plasma. A statement provided to ProPublica and ARD said that donating plasma is now considered "labor for hire," which is illegal under the visitor visa most border residents use to cross into the United States to make donations….

Could they just set up plasma donation stations in Mexico and ship it to the US?

I think the logistics would make it too expensive. Also there might be rules and regs from the U.S. that prohibit blood products from being imported.

Probably, Red tape. My wife has MS and she would love to donate blood but they won't accept hers.
