What are the visa & residency requirements in Libya?

"In order to visit Libya, foreign nationals must obtain a visa prior to arrival. The process of applying for a visa involves submitting an application form, a valid passport, two passport-sized photographs, and a fee to the Libyan Embassy or Consulate in the applicant's home country. In order to obtain residency in Libya, foreign nationals must first obtain a residence permit. This permit is issued by the Libyan Ministry of Interior and requires the submission of an application form, a valid passport, two passport-sized photographs, and a fee. The applicant must also provide proof of employment or a business license, proof of sufficient funds, and a medical certificate. Once the application is approved, the applicant will be issued a residence permit," remarked another expat in Libya.
