How long do I have to convert a vitas to a marriage kitas ?

I'm totally confused at this point. Some websites state 7 some say 30 days. My wife's ktp and kk are not ready and I am using an agent to finish them but I could get some breathing space if it's 30.
I know that this might be a frequently asked question so apologies if so.

it must be 30 days,it is require to report in immigration,reporting and you will be schedule for photoshoot and biometric.Our company processed,related on this,you must proceed paying merp etc. once you got your vitas and arrived here in indonesia.
