學歷認證係咪做最高學歷就夠？

你可以參考 IRCC 嘅以下網頁：
What credential should I get assessed for immigration purposes?

另外亦可以參考 WES 嘅以下網頁：
Requirements for Canada’s Educational Credential Assessment (ECA)
https://www.wes.org/advisor-blog/requirements-canada-educational-credential-assessment-eca/

網頁有提及 “In most cases, you only need to submit your highest credential for an ECA”。
