Some of them are too old to move outside.My best financial advice for Iranians is to start working towards a second residency or citizenship ASAP.
Others already do.
I know. But they want to use it to buy things from outside of Iran.Btw. Visa and MasterCard don't work in Iran
A few years ago, I tried to establish a company importing things to Iran. (No dual-use goods or anything military. Mostly clothes)
We could manage to get money out of Iran (via an Asian country) and found dealsers (also from EU) shipping to Iran directly.
It was somehow win-win. The dealers took the normal price including VAT, but could declare it for export. So they did not have to pay it.
And we were lucky, that they sent everything to Iran directly.
The big problem was the bribe we had to pay to the Iranian customs. They charged at least 200 $ to open the packet, took some stuff out of the packet (in front of my peer in Iran) and then charged some additional import tax for the remaining items.
And so the project failed. But that is a different story.
Nevertheless, many people from Iran would be very happy, if they could easily shop items from other countries.
They were willing to pay double the normal price for H&M clothes, for example.
