Jeg fant litt mer informasjon her:
There's no simple answer as each case is different however, if your 2 friends didn't go to jail for more than 12 months then it shouldn't be a problem.
It's all about 'character'. Normally (remember each case is different) an offense that didn't result in jail time of +12months will not fail a character test. There obtaining a visa would be possible if all other aspects of the process were meet.
If they did serve a jail time of 12 months or more than it becomes difficult, you have to prove their character and this can become hard and delicate.
To give you a definite answer they would need to sit down with an agent.
My advice would be to use an immigration agent to assist with your friends application.
Dette er dog angående en kokaindom (snakk om et stakkars gram som ikke resulterte i fengselsdom). Men nå er jeg egentlig lei av å google for deg. Dette er ting du kunne ha funnet ut helt selv hvis du bare hadde tatt deg tid og giddi å søkt på google selv.
