A tourist visa to Afghanistan can be extended only once, for 1 month. The cost for overstaying your visa is now $10 per day overstaying during the first month (instead of $2 per day previously), and $15 per day for the second month (previously $5 per day). If the delay is more than two months, in addition to the fine, you will be deported.
