tldr: Exchange first, bring less cash.
You can bring that much and generally have to declare bringing in any amount of cash over 10,000 euros into the EU.
I’ve been traveling 15 years and find that currency exchange heavily depends on your currency and local facility of exchange, so:
i have no doubt you’ll be able to find a money changer that can exchange rial and dinar, but since they’re not as popular as other dominant currencies at the moment, it is worth checking prices in your area before you go.
If you can find a place that exchanges under 5% nominal exchange rate, there’s a good likelihood that’s a better exchange rate than you’ll find upon arrival in the EU.
Many people turn back to crime because they still don’t feel like they have a choice.
Countries with lower recidivism focus on providing the social support people often need to rejoin and contribute to society.
The focus of most US incarceration systems is profit; to exploit criminals for their near-free labor while receiving taxpayer money to house those criminals.
Additionally, most states in the U.S. charge prison inmates for their incarceration. This policy is almost never referenced in TV or movies, but 42 states and DC have “pay for stay” incarceration legal frameworks, so a prisoner can be charged for meals and rent and medical care every day they are incarcerated, then get out of jail or prison in the US and be in more debt than when they went in.
It’s also difficult to get a job as a convict in the US and get access to social support, so without any legal way to support themselves and no viable social framework by which to rejoin society, many US criminals feel forced to fall back into criminal activity just to pay for rent, food, and their children.
