It seems your employer should be able to answer your questions as to why you may not be able to sponsor your family. I'm a woman and I sponsor my two children and my husband. I know several women who sponsor their families. My residency permit and the sponsorship of my family happened fairly quickly. I did not encounter any problems. The only thing I can think of is the money factor. There is a minimum amount of money you have to make in order to sponsor a family but I am not sure what the minimum is.
