Poland Student Visa – Apostille Question for Indian Class 12 Documents

Hi everyone,

I’m an Indian student applying for a Poland D-type national student visa for my Bachelor’s studies at Vistula University, Warsaw.

I’m a little confused about the apostille requirement for my Class 12 documents and would really appreciate advice from anyone who has recently applied from India.

My documents are from ISC (Indian School Certificate) Board, Uttar Pradesh.

Currently I have:

Class X Statement of Marks — apostilled

Class X Pass Certificate — apostilled

Class XII Pass Certificate-cum-Statement of Marks — apostilled

I also have a separate Class XII Pass Certificate, but this one is not apostilled

My main question is:

Since my Class XII Pass Certificate-cum-Statement of Marks is already apostilled and I have the NAWA recognition/individual information document, do I also need to apostille the separate Class XII Pass Certificate for the Poland student visa?

The visa checklist I received says that for a first-year Bachelor's applicant, the higher secondary certificate must be legalized/apostilled and accompanied by the NAWA recognition statement.

Has anyone with an Indian/ISC Class 12 certificate recently applied for a Poland student visa and can confirm what documents they actually submitted?

Also:

Did VFS/Embassy ask for a separate Class XII Pass Certificate?

Was the apostilled Pass Certificate-cum-Statement of Marks sufficient?

Did anyone have an apostille issued through Delhi/MEA for an ISC certificate issued in Uttar Pradesh?

Approximately how long did the apostille process take?

I’m trying to make sure everything is correct before submitting my visa application. Any recent 2025/2026 experience would be especially helpful.

Thanks!
