my friend got approved within a week

Depends on the case, usually within 60 days.

okay,@zaki mohas that is really good information

@Judy Loc the maximum is 60?Do you know if incase it exceeds 60 days does it mean something is not right with your case

@temex tinix It does work as they are legally bound to give you an answer.

@temex tinix if after 60 days no response, they ignore your mandamus probably because you didn't have good written mandamus, you didn't file it properly or with proper forms, you didn't serve properly, etc... thus they don't care... Always get help from someone who knows a good deal about mandamus. Search youtube "writ of mandamus pro se"
