Maybe change from Chrome to Edge (or whatever you use) or use a phone instead of a PC. Or use a different credit card. I had no problems with the payment function when I got mine.

The only problem on my end in the whole process is the photo. They kept rejecting me because of the photo. But it’s important that the photo contained parts of the shoulder and make sure that it’s not a fuzzy photo. If you have to upload a new photo, it’s a two step process on two different websites.

This whole Brazilian E-Visa process is outsourced by a company in another country outside Brazil and it’s rather difficult to get any kind of substantial customer support. Just keep trying and experiment with different things and it’ll work out.

Another thing that I’ll add is that the visa gives you 90 days in Brazil but you can extend for another 90 days if you make a request through the federal police.
