I also understand the so called Wet Foot/Dry Foot policy refers to the 1995 revision of the Cuban Adjustment Act of 1966. Prior to this Cubans picked up at sea were allowed to pursue residency just as if they had reached US soil. The 1995 revision, negotiated by the Clinton administration with Cuba stopped this practice and there after Cubans intercepted at sea were returned to Cuba. So technically the "Wet Foot/Dry Foot Policy" only relates to Cubans.
On a slightly lighter note, the government even has problems dealing with this issue. Back in 2006, a group of Cuban illegal immigrants made it to the old 7 Mile Bridge down in the Keys. Since the old section of the bridge is disconnected from the island on each end, the government held they were not on US soil. This lead the people in Key West (AKA The Conch Republic) to plant the Conch Republic flag on the bridge and claim this "unclaimed" territory as Conch Republic territory. Shortly there after the government revised it's opinion and the Cubans were determined to have been "dry foot".
