You MUST apply for a new visa BEFORE your current visa expires. We strongly advise you seek the assistance of a migration agent experienced in refugee visas at least 6 months before your visa expires.
AMO is able to assist with these new applications for clients all over Australia.
If you do not apply before your current visa ceases, you may not be able to apply for a subsequent visa and you will become illegal.
Lodging the new application in time ensures your visa and any associated benefits will remain in effect until your application is decided.
