The most straightforward option for you is to create a Bulgarian company and create full-time jobs for at least 10 local people. This will enable you to obtain residency for yourself. Your wife and children will be also eligible for residency, based on your status in Bulgaria. If your business partner intends to obtain residency permit too, the number of employed people will need to be at least 20 (10 for you and 10 for him). Employing 20 people may be done through one single entity (a company), where you will be co-shareholders with your partner, or in two separate entities.
