What if checklist pdf

Please check out our troubleshooting tips if PDF files do not open. To process an application, we need all the documents listed in our checklist. The processing time begins only when we have received the documents. For some documents, certified photocopies are mandatory to confirm that the photocopy corresponds to the original. It bears the official stamp and signature of the certifying authority.

The checklist indicates for each document if a regular or a certified photocopy is required. The ZAB needs an overview of your entire educational path to evaluate your university degree, including the kind of secondary school you attended and graduated from.

There is a considerable variety in educational systems of different countries. Therefore, we may need different documents to evaluate degrees. In the checklists, we included the most important terms in the language of the respective country to make the application process easier for you.
