hi gang!

i know SOMEONE will have an answer for this one...

what are the requirements for a belizean citizen to obtain a visitor's visa to the usa?

are the requirements different for a student as opposed to an adult?

if i am the person writing a letter of invitiation to a belizean to come to the us, what are my obligations or responsibilities while that person is in the country? whom should a letter of invitation be addressed to? the visitor? does s/he then submit it with the other paperwork for a visa?
