Gringo here, I've been thinking of immigrating to argentina in the future (still have A LOT to plan if I want to make the move) and im nervous about it socially, do you have any advice?
I do, actually have some advice. This country welcomes immigrants with open arms, you'll have a very easy time coming here and an easy time becoming argentinian by law. First, learn Spanish. Don't come here pretending that everyone speak to you in English. Second, the people will share food, drink and culture with you.
It is imperative that you try what is offered to you
the difference between a settler from the Global North coming to gentrify and someone who genuinely wants to share in the beauty of being human is whether they believe they're above us or not. Please don't be that person. If you're offered mate, at least try it a few times. It won't be yummy at first for most people, but you can add sugar or milk to make it more palatable until you get used to it.
People will kiss you on the cheek, hug you, pat you and generally be more into contact than anyone on the USA or northern Europe. let them. Don't be a jerk, refusing a kiss on the cheek here is pretty much a sign that you don't like that person. Become familiar with casual affection, it's one of the beauties of Argentina.
Please shed your ideas of food availability. Food is extremely expensive in off season here. Adapt to this. Forget about year round cheap fruit and learn about winter mandarinas, summer melones, and so!
Clothes: buy them at ferias instead of shops. You'll be participating in popular economy and not gentrifying.
Get a job here, please. Don't be a digital nomad, that's the top 1 Gentrificator these days and it makes everything shittier for Argentinians in the long run.
Get used to being lovingly teased for your traits. You'll probably get a nickname if you make new friends, based on your traits both physically or socially. For example, I get called Laucha (a kind of small rat) because I'm small and my name starts with the same letters. This is my badge of pride even if I dislike rats. It means people around me love me.
