Hi All,
I have been living in Germany for a little over 5 years and would like to apply for Niederlassungserlaubnis. I wanted to know the documents required for the application. My husband has his Niederlassungserlaubnis and since I have not been working in Germany I will be applying as his dependent. The following are the documents I think are required (gathered after researching on the internent). I have posted the question to the Landratsamt, however I have not got reply from them  

 Could you please help me and let me know if I have got the list right or if Im missing anything. 

1. Application form for a residence permit 
2. Passport 
3. biometric photo 
4. Family reunification with spouse: marriage certificate
5. Language certificate / Certificates for the integration course
6. Proof of secure livelihood (Husband's proof of income)
7. Health insurance
8. Certificate of registration of the apartment (confirmation of registration)

Thanks for your help.

Regards,
Davi
