So I want to know this how and when I can apply Germany Passport ? So please Help me About my Question..

You are currently not eligible for a German passport. You can get a German passport after you have been married for two years and have lived in Germany for three years. At that point, you can apply to become a naturalized German citizen. Once you are a German citizen, you may apply for a passport.
