I'm happy to see SeekingTruth's concern for the safety of foreign drivers. They must have the same problem as American's do when driving in other countries. Best to know what  "alto" or "curva" means! We seem to catch on rather quickly when driving in other countries. I suppose the same for others who visit America.

Sadly, refugees are often desparate. Our Immigration laws do account for some of those in need. But the need is often more than our present laws allow for, and people who are in danger of death by terrorists or starvation are often desparate enough to hope that the sign we put on the Statue of Liberty might still have some meaning.
