If you are talking about family visit visa for 6 months, your salary must above 7000 before the accommodation, and you have to have a certain job title. If this part is ok, your next step is to obtain a NOC from your sponsor, to get a passport copy of your spouse and the proof of your relationship. All these papers you submit to the immigration office.
If you are talking about 1 month family visa, only your Job title matters. You gather the same papers and submit them to the Airport Visas section.
