His new wife wants to apply for the sc500 subsequent entrant visa. So he wants to make sure all their details are consistent, and that dibp are aware of their relationship should dibp go digging for information about their marriage. Like, if the wife applies to join him on sc500 sub entrant visa, and dibp notice my friend's details show 'Single', wouldn't they think something is suss? I'm sorry...I don't know how this all works and just as confused as my friend is. Just seeking some clarification.
Did he include his wife's details at all in his 500 application?
If not, then she may not be able to apply.
Fom DIBP:
"Your eligible family members can:
* accompany you to Australia if you have included them in your visa application.
* join you in Australia after you have been granted your visa as a subsequent entrant.
You must have declared these family members in your student visa application.
Declare all family members on your application, even if they do not plan to travel with you to Australia. If you do not do this, your family members will not be eligible for a student visa to join you in Australia.
If you did not declare a family member and they need to join you in Australia at a later date, you will need to apply for a new student visa including them and explain why they were not included on your application. An exception to this is if they became your family members after your student visa was granted and before a subsequent application is made."
From my understanding, he may need to get a new visa if she wants to join him.
