Problem:When I came to Chile, I originally thought I would only be here for 1 month, so that's what I put on my tourist card.

However, now there's a good chance I'm going to stay the full 90 days that my tourist visa allows, and I might even want to extend my visa after that.

Can I wait until the 2.5 month mark to extend my visa, or do I need to extend it 2 weeks before my "declared" trip ends (i.e., within the next 2 weeks)?

Solution:
Extend my tourist visa toward the end of my "declared" trip or wait until closer to the visa expiration?
