visit visa to family visa

You can go to MOI in Sharafeyyah and submit one paper after writing that you want helping them to convert your visit visa to Iqama, there are people there can write to you the paper, and note that the profession of your husband in Iqama must allowed him to make Iqama for you.
other way I saw ads that some people can make it for you but they take money, if you like this don't give any money before getting Iqama.
This one of them he can make it as he write in ad. 0597844997 Abu Faisal

A visit visa can be converted into a permanent residency permit for a close family member of an expatriate worker under special conditions, a senior Passport Department official said during a phone-in service with Arab News readers on Wednesday.
Yes, this is possible, said Col. Mohammed Al-Hussain, spokesperson of the department. However, such a request has to be approved by the Interior Ministry.
