Proof of Address, I am American Citizen

You’re here illegally, have been illegally gambling and spoofing your location, now you’re asking for help to get hold of your “ill gotten gains”.

Not many of us here are keen on promoting illegal activities.

Yeah, no.  You’re on your own with this one.

agreed!!

playing poker is only good in Texas saloons! hahaha

your mom did not tell you that playing money is a sin? :-)

good luck!

Anti GTO,
You went all-in with no cards. You are an illegal foreigner in the eyes of Brazil.
You face a fine of $R100 per day over your visa days granted. I would suggest trying to leave Brasil on your own or face deportation.
Many such sites have come into question by the MJ and have started enforcing Brasil regulations. Pokerstars can lose any licenses.
In 2014 a new law was passed in Brasil governing the use of the internet for many things, one being gambling. Gambling is legal in Brasil since 1943, but all such commercial places/sites must have a license.
So we addressed question 1.
Question 2. I see no avenue in seeking residency. You could try an investor visa by investing $R 500.000,00 in an established busness, but you will face the music as to being here illegally on any visa application

Anti GTO,

There's no practical way to regularize your situation.   Time to plan a rapid, orderly retreat from Brazil.

The Federal Police are serious as a heart attack when it comes to enforcing the immigration laws.  If you go there,  they will probably give you a date in the very near future by which you need to leave the country,  and a bill for your overstay fine at the rate of R$100,00/day, to a maximum of R10.000,00, which you'll be expected to pay on departure.   If you can't pay, you'll need to sign an agreement to pay on your return,  and interest will accrue until then.

If you just buy a ticket and go to the airport, they'll present you with the fine before allowing you to board your flight, under the same terms.

In discussions with the Federal Police,  it would be best to avoid any reference to how you make your living.  Brazil does not ordinarily arrest foreigners for visa infractions;  suspicion of illegal activity or tax evasion,  however,  is another story.

First, since you stated “I am a professional poker player… moved to Brazil to grind poker with a friend,” you entered Brazil with the intention to work, without a work visa.  Then you intentionally overstayed your 90-day visa, just 3-months, by a full 7-months’ time having admitted you have now been in Brazil for a full 10-months.  The fine for overstaying your visa is R$100,00/day, up to a maximum of R10.000,00, plus interest, which you have reached long, long ago.

Having a CPF had nothing to do with residency. It is not any form of documentation to demonstrate you have any rights to be in or to remain in Brazil. “The Cadastro de Pessoas Físicas (CPF; Portuguese for "Natural Persons Register") is the Brazilian individual taxpayer registry identification, a number attributed by the Brazilian Federal Revenue (Receita Federal do Brasil) to both Brazilians and resident aliens who pay taxes…” ( https://www.fearp.usp.br/en/index.php/s … ~:text=The Cadastro de Pessoas Físicas,part, directly or indirectly, in ).

With regard to your questions, you have already answered your first question.
Question 1, for proof of residency, you will need, (your own list):
Utility bill (gas, water, electricity)
Employee letter/payslip
Landline / internet / TV bill
Tax or Government letter
Insurance documents
Bank statement or another financial letter
Rental agreement
Mobile phone bill
Residence certificate

Question 2, If you cannot demonstrate any legitimate reason you have so far over-stayed your visa by 7-months, you are likely to be deported.  You can also be blocked from re-entering Brazil for years.
***
My suggestion is only to formulate a sincere exit plan, now, to leave Brazil and to pay your full fines as quickly as possible before this becomes more serious. Yes, Brazil is strict about their immigration laws and rightfully so, it is their country.

I appreciate the replies and want to thank those of you that provided sincere and detailed answers without judgement.

Anti GTO
I keep thinking of a pre-paid cell phone. If you live with someone and they allow you to use such you have an address.
I know for a contract phone, you cannot get such without a lease agreement, bank statement, and all that you cannot get on a tourist visa.
You have that BIG immigration cloud though.
Good luck
