- ✅ Professionals seeking jobs abroad or in international firms
- ✅ Immigration and visa applications (e.g., UK, Canada, Australia, USA)
- ✅ Teachers and translators needing proof of near-native command of English
- ✅ Corporate or academic roles requiring high-level English communication
🏛️ Popular English Proficiency Certificates
