• Long-term residence permit- up to one year
• Permanent residence permit-for an indefinite period of time

• The long-term residence permit can be renewed if the grounds for its issuance still exist at the time of the renewal.
• An extension of the long term residence permit can be refused if it is established that the foreign citizen has not stayed on the territory of the Republic of Bulgaria for at least 6 months and one day during the preceding calendar year.
• Foreigners who have been granted long-term or permanent residence in the Republic of Bulgaria and the family members of a foreigner who has been granted residence permit can take up employment in the manner provided for Bulgarian citizens

Foreign citizens who have obtained a long term residence permit have all the rights and obligations granted to or imposed on the Bulgarian citizens. For example, they can be employed by Bulgarian employers, receive social security compensations, health care insurance, etc. Long-term residence status for a foreign citizen is usually evidenced by the issuance of a Bulgarian ID card for the foreign national.
