Apostille for American High School Diploma (International Schools)

The American High School Diploma has become one of the most internationally recognised secondary school qualifications. Offered not only in the United States but also in hundreds of international schools worldwide — including many in Switzerland — this diploma provides students with a flexible academic foundation, college-preparatory coursework, and a pathway to global higher education (Apostille for American High School Diploma).

However, even widely recognised credentials require formal authentication when used overseas. Many universities, employers, government agencies, and immigration offices demand legal proof that a diploma is genuine. That is why an apostille is often essential when presenting an American High School Diploma abroad.

An apostille is an internationally accepted certification that validates the signature, stamp, or issuing authority of a document. Countries participating in the Hague Apostille Convention require this additional verification before recognising foreign educational qualifications. Without an apostille, applications abroad — including university admissions and visa submissions — may be delayed, returned, or rejected.
