Sharing: 6 months visitor Visa extension

Was anything else required besides the pesos?  I was under the impression that if you wanted to stay more than 6 months then certain health tests were required.

Does it allow for multiple entries?

I messengered BI and they said no mutiple entry. But ask another person they may say yes. Still researching it.

No. Just pay the required fee.

No.

I don't  know .

They require nothing beyond the fees and of course, your passport and an ACR card if you don’t already have.
The six month extension is not a multiple entry visa.

You are correct
