The problem
The reality for foreign workers in Croatia
The new law doesn't ask — you either have the certificate or you go home.
The new Foreigners Act
Since 2024, every foreign worker has to prove A1.1-level Croatian to renew their residence permit.
Short deadlines
The deadlines are strict. Without the certificate the permit isn't renewed — and that means going home.
The language barrier
Traditional courses are expensive and don't speak the worker's language. It takes a platform that understands their mother tongue.
The law is in force
Under the Foreigners Act (NN 133/20), foreign workers must prove A1.1-level Croatian (HEP scale) when renewing temporary residence. Crolingo is designed for exactly this.
