Cheryl -
I, too, will "cheat a bit," since my first experience of Brazil was in 1965 when I came as a 17-yr-old participant in an American Field Service (AFS) exchange program. But I think my recent experience is more what you're looking for.
To fill in some gaps, however, I took 4 years of Portuguese classes in college and also maintained contact through visits with my Brazilian host family over the years. Mostly. Fast forward...
In 2019, I was ready to retire and began to explore places I might like to move to from Missouri. I knew I wanted easy access to Brazil and considered Florida. However, I became aware that Brazil had recently made available the new "retirement" visa category for which I seemed to be eligible. I applied just prior to covid shutdowns through the Chicago consulate (and, I might add, with advice and encouragement from members of this forum). I did not use an agent; I collected and submitted all the paperwork myself. Well, almost all. I wanted to bring my aging canine companion with me and I did turn that responsibility over to a pet relocation service out of Austin. Very expensive, but I have no regrets. I had enough on my plate. My plan was to arrive in March or April 2021. All my paperwork was mailed to the consulate in January. I had expected to have to go to Chicago for an in-person interview, but covid closed it down and everything was done by email and US Mail.
In November of 2020, I made an "exploratory" trip to Brazil. I wanted to confirm I had the moral support of my Brazilian friends, which I did, in spades. With their encouragement and co-signing, I actually found and rented an apartment in the same building where the daughter of an old AFS friend lives. I returned to the States (apartment rented, but still no visa even applied for at that time; ONLY possible due to personal connections, believe me). Yes, I paid for an empty apartment for 3 months, but at US$325 a month, it was just one more expense I budgeted for. I looked at 3 or 4 places, some more expensive, some less, but I chose this one for its size (3 bdrm), proximity to services (no car), and the in-building support offered by my friend's daughter.
The day of my arrival in mid-March, I was greeted at the airport by my host family from 1965. My apartment had been decorated with balloons and welcome signs and, best of all, a couple of chairs, a small desk, a mattress and a microwave, all prepared by my neighbor friend, all on loan. My dog was delivered to my door the day after, confused as all get out, but safe and healthy. We were home.
I quickly got into furnishing the place. Besides clothes and personal items, I had packed minimal essentials: a frying pan, a medium pan, table service for 4, a set of bed linens and towels, etc. in my 2 almost oversized, almost overweight (but neither) bags. I had also left some clothes and cleaning supplies in one of the rooms when I had rented the place the previous November. Other than drinking water and power, I had enough to get by until I could get out.
My friend had a decorator friend who was instrumental in helping me get settled. At that time, the city was pretty much totally shut down due to covid, but with her connections, we were able to contact shop owners who let us in for shopping or who brought things out to show us. Besides furniture, I also needed a basic stove, fridge, my own microwave, water dispenser/cooler and washing machine. I was actually lucky to be shopping during covid times. My "consultant" had abundant free time to help me, and the shop owners were eager for business. I was pretty much settled in in less than a month.
It's noe been over two years, and I have felt very welcome and much at home due to the above support. Also key, I believe, was speaking Portuguese and having my dog. She forces me to get out a couple of times a day and we are recognized and greeted by building residents and neighbors on the street. My social life here almost entirely consists of the friends I've made through pickleball. We have 3 active clubs in town and I play at all. I recommend finding some kind of group to affiliate with, be it pickleball or other sport, church, or a social club.
Incidentally, MigranteWeb today showed my visa extension was recently approved, but no email confirmation yet.
Happy to be living the good life.
