Defending a criminal case to avoid jail and deportation

Hi Sir,

My friend and his friends have been caught for having drugs at their home, and police came and caught them at home. They took them to jail and the results have been positive.

As they are students of the final year, it is difficult to finish their career when they will be deported or put in jail as by 3 months their college year will get over.

So, it will be helpful if they remove the deportation and jail sentences for their career and future.
