Kia Ora,

My wife applied for the partnership visitor visa and I have following questions if someone can please clarify
- The case officer has been assigned and she asked questions to clarify a few things about the relationship. The answers were submitted within the given timeframe.
- After submitting our answers, When we didn't hear from CO, We sent an email to her. She responded back saying that the application is in "the final stage" and she should be able to update us within a week.
- After a week, we checked again with CO asking for an update on the application, she responded saying that "the application is undergoing internal verification, this can take upto 5 working days"

I am not sure what does it mean by the application is in the final stage and application is undergoing internal verification, Can someone please advise?
