How long does it take for an Offshore Partner Visa Application to go from further assessment to visa grant?
A: It depends how long it takes the immigration office to review/check/confirm the information you have submitted.
This can vary between different applicants, and what extra information they had to supply.
I have seen people say they got the grant one day later, but others were still waiting a year or more after submitting the extra information.
Some never even get to the further assessment stage, going direct to grant from initial assessment.
On our subclass 300 visa it would have been about 4 months, but that was back when offshore visa grant processing was much faster.
