How long is is the visa progress time for approval

Hi,
I am an South African female teacher, applied for my work visa six weeks ago this is the seventh week. The company is expecting me on the 19th of August. I have been patiently waiting for my langsvisa. Problems is the days are getting closer and not outcome from the embassy. How long is this process and is there anyway I can findout the status. If I should be hopeful its working?

Many Thanks

Visa approval can take three months or more in some cases.
Ask the embassy for the status and expected processing time of your application.
