​ [Case Study Sharing] Today, we're discussing the issue of submitting a student visa application within the validity period of an onshore visa but not receiving a BVA, as well as the situation of submitting a new student visa application after the expiration of the onshore student visa.

With the end of the peak period for visa renewals on March 15th, many students have chosen to DIY their student visa renewal in Australia but have also faced some issues. We've received some related inquiries, so today, let's share some case studies and solutions to help everyone smoothly apply for their visas.

Firstly, let's understand two types of visas: substantive visas and bridging visas.

Substantive visas include tourist visas, student visas, work visas, etc.;

And the bridging visas A, B, C that we commonly see are visas obtained after submitting a new substantive visa application onshore.

With this understanding, let's proceed with the case studies:

Case Study 1: The applicant submitted their visa application themselves before the student visa expired but did not receive a BVA. The reason was incomplete information, such as an incorrect date of birth. Remember, it's crucial to provide accurate personal information; otherwise, the system won't recognize it, and a BVA won't be generated. We promptly helped the student correct the information and contacted the immigration department to resolve the issue. Eventually, the student successfully obtained a BVA and legally remained in Australia awaiting visa approval.

Case Study 2: Grace Period is an important concept.

For onshore student visa applicants, you need to hold a substantive visa without the ‘No Further Stay’ visa condition at the time of applying for a new student visa.

For example, for onshore student visa applicants, if your student visa expired on March 15th, and you're in Australia at the time of applying for a new student visa, you only
