I was in your situation a few years ago. But I didn't encounter attestation of my educational degree for wife's or family visa application. Maybe it's the new rules. To be sure, ask the labor office. Your work certificate from the army states your profession. Isn't it? If you submit your papers this time you will get a feedback of what other requirements to be done. So what's the risk? What is there for to you hurry and get your wife to be with you as soon as possible? You must be a newly married to do that. Strike the iron while it's hot huh?
