There is no such rules that you have to wait for 6 months for applying for your family visa. However, you should have your RP formalities (medical, finger print, RP stamping etc...)completed before applying for your family visa. Under normal conditions, it takes less than a month. Also for family visa, you have to make sure that the job mentioned in your visa qualifies for family status. Some times, companies offer good job, but fail to get labour approval for the same and apply for visa for different job title and get approval. This may not affect the position or job in your company, but may affect getting family visa. If your job title is good and you earn good salary, it normally takes less than a week to get family visa approval.
