You can sponsor your husband and child as long as you meet the requirements, e.g. job title, salary, noc, bank statement but if working for a government company no need for bank statement. You have to get confirmed first before you sponsor your family, ussually its a minimum of 3mos. After that you can apply for family residence visa, ussually if no problem, it will take for 3-4 working days only, but if there is a problem, it will take long. Once they are here, processing of their rp will take only maximum of 2 weeks. Children below 12 yrs old no id is provided just rp stamp on the passport. I just got my husband and child this march. They already got their rp. Best luck.
