it has never come up before....
Do you think it would present a problem to have two different visas (tourist and business) ..I appreciate your advice.
It is impossible to have the two visas at the same time.
The reason is that whoever ask the entrance in the Country must be invited by some one, private people, official, T.O,ecc that become responsible of whatever problems may arose.
So talk with your friends,wich is prerefable for them , a tourist visas or the businnes one?
As a rule the bussiness visa is issued by companies,the tourist by T.O., in this case the problem is not mainly your, but to your friends that invites you and as to fill the application forms in Libya for the letter of invitation.
