Depends, for example if you have a valid Canadian/American visa and Indian passport, you don't need a visa to travel to Mexico.

A lot of countries grant visa free access to holders of e.g: us visit visa or schengen residency, they call it a substitute visa

I had no idea about this. Thanks! For anyone, curious here are the countries you can travel with a US visa.

I think countries on the border will allow travel, so if you have an Australian PR you might visit New Zealand, a US GC for Mexico or a China residence visa for Honk Kong.

(I am not saying those visas are currently accepted, I am saying they might be)

Yes, there are some visas which are useful. Will add it soon.
