I can help you to obtain visa
first there is no “journalist” visas so far there is a press pass ,
you can have :
1- tourist visa
2- mission visa
3- multi-exit visa visa for three months and six months .
if you ask they will tell you that you need invitation letter and etc
but all what you really need is someone who can get you the visa + copy of your passport
you can collect the visa at the airport when you arrive or at the Libyan embassy in your country
it will take between 3 to 7 days
