However, you can convey the meaning using descriptive phrases:
* பயண அனுமதி (Payana anumati): This literally means "travel permission" and is the most common way to refer to a visa in Tamil.
* நுழைவு அனுமதி (Nulaiivu anumati): This means "entry permit" and is another option.
* விசா (Visa): You could use the English word "Visa" directly, as it is understood by many Tamil speakers.
The best way to say "Visa" in Tamil will depend on the specific context and your audience.
