Hello - I have read a lot on this forum for quite a while. Very interesting place to be spend time reading about aquaponics.

I have a question. A little off the regular discussion items that I see here but want to ask it and would appreciate your help.
We started an Aquaponics AAS Degree Program at Dakota College in North Dakota this semester and have 3 students. I struggle with finding students in our state but have had some success finding students outside of the USA that are interested and want to come here(don't know why--its cold here!). This summer we plan on having an internship and now I have students outside of the US wanting to fill those internships. The internship requires that they get a work visa. What are the steps to get the work visa?
