What's a skill that's taken for granted where you live, but is often missing in people moving there from abroad?
I was thinking about that when I was dropping my 6 year old off at some hobbies earlier - it's pretty much expected to have learned how to ride a bicycle before starting school, and it massively expands the area you can go to by yourself. When she went to school by bicycle she can easily make a detour via a shop to spend some pocket money before coming home, while by foot that'd be rather time consuming.
Quite a lot of friends from outside of Europe either can't ride a bicycle, or were learning it as adult after moving here, though.
edit: the high number of replies mentioning "swimming" made me realize that I had that filed as a basic skill pretty much everybody has - probably due to swimming lessons being a mandatory part of school education here.
I feel like Latin Americans in general take for granted that you're supposed to pull and push everything to make it work. Sometimes with clever but shitty and overspecific solutions for the problem, or shifting the goals to something more achievable. Some examples:
Three examples:
::: spoiler home oven
The top of the inner part of your oven is partially corroded, so the top heating element does not stay in place. If you leave it as is, it'll get in the way, burn you, and burn your food. And you don't have money for a new oven. You're reasonably sure that the heating element is coated with some elec-proof stuff.
So what do you do? You put a big nail across the hole caused by the corrosion, and hold the element to that nail with some wire. "Just temporarily". (Nothing is more permanent than temporary hacks.)

::: spoiler Linguistics, field work
Linguistics. You're making field work on phonetics. You need clear records of speakers speaking their variety, that means good mic + noiseless environment. And yet you're studying a variety mostly spoken by farmers, and the ones willing to help you out can't travel, so you'll need to record them from a cellphone in their farm, and your record will be filled with pigs oinking, birds chirping, and a rooster going "CRAAAA" nonstop.
The solution? ...screw phonology, your paper is now about syntax. It's far easier to detect by ear if the speaker used pronoun reduplication than if he used [ɾ], [ɹ] or [ɻ].

::: spoiler Chemistry, organic synthesis
You got a synthesis route demanding glacial acetic acid (HAc). Except that the HAc bottle is empty, requesting another will take a week because bureaucracy, and oxidising ethanol to HAc through permanganate is bound to get someone screeching at you "YOU'RE WASTING OUR REAGENTS!!!".
Your solution? Run some quick maths on what's cheaper: 1) to distil supermarket vinegar, or 2) to use bleach to oxidise ethanol at some loss. Then you do it.

Ah, on a more local area, Paraná: whisking homemade mayo for the Sunday potato salad. One does not use bottled mayo for that, it got to be handmade.
In India we call this sort of engineering 'jugaad'. And we do it all the time, sometimes to a dangerous level.
