A citizen of the United States and resident of Arkansas would need to have a valid drivers license.
Possibly a person on a legal visa could use an international drivers license for the term of their stay if allowed under state law.
However, a person on any kind of visitor visa could not work because they would not have a Social Security number.
It also helps to have a relative who lives in the area and has followed this story for some time.
Now if you know for sure the 42 individuals involved are American citizens then I might have to redo my former post.
