Family reunification

Hello!

Is here anyone who got married to a Romanian citizen? I am Romanian and i want to get married to an Algerian in his country. I checked on IGI site the documents i need to apply for family reunification, so he can come here and live with me, but something is a bit unclear to me. I saw that i need proof of support (money) - "The amount you must own is the equivalent of the minimum national net wage, for the entire validity period of the residence permit", but how could i know the valability of the residence permit? How much money should i have in my account?

i don't know if i explained very well what i want to know, if not, i'll try my best again.

I think the ones who applied for family reunification could help me with my questions.

Thank you in advance and have a good day!
