You are going through the normal process. So expect about a month or to get your RP.

Depending on your husband's company whether they want to step in to influence or not. OR whether you know anyone in the medical clinic who does the check up.

Normally, you need to apply online for the medical check up which will then give you a date. If there is someone helping you, you will be informed of the date every soon, like within a day and your check up is the next day.

If you know people inside, even faster. You don't even need a date or book online. You just go to the check up, the "insider" will have you do the medical within 15 minutes, and the results out within half a day, and you go for your finger printing, and the next day you get your RP.

Of course there are some "conditions" which cannot be listed here.
