In my country, which is Venezuela, it is somewhat complex to get money from outside, so one of the best options is Amazon and its gift cards. Is it feasible for me to ask for payment in that format instead?
If you are asking about the convenience for companies in the United States of America some may have issues with sending gift cards for fear of possible IRS ramifications. I had once asked a similar question and that was the response I had received.
It would also depend on the size of the company you work for. You are more likely to get paid in gift cards if the business is sole proprietor or small group.
Although still in its infancy, and depending on its legal status in your country, Bitcoin or other digital currency may be an option. Imho, nothing compares to the ease and quickness which it can transfer wealth.
Either way It doesn't (shouldn't) hurt to ask. Unless of course it may be perceived as a tax dodge of some sort.
Yes, you can ask for this. Maybe some will find it a bit unusual but it could work. A lot of companies buy these cards to give as corporate gifts and have piles of them. I think these cards are also easily available in stores and groceries or online.
The issues I could see with this is:
1) You get sent cards that were already used on Amazon. But you can always verify this when you get them.
2) It's a bit like being paid in cheque/money order... so ideally you would need to wait until you get the cards before sending your final files (if there are final files in your field of work.) As you guess this could make some clients a bit impatient/worried. You'll need to think of a system to not end up working for free and to also make the client trust you; they might not all understand the reason why you ask for this.
I guess you already explored you other options but I'll add this in case you didn't.
Money order? That could be safe.
Western Union should work but the fees are usually quite high.
Apparently it's possible to use Paypal but the administrative process from your country can take a few months and the amount you can get on the account is limited. But maybe you could combine this method and other methods.
There's Visa gift cards that are like prepaid credit cards and can be activated safely.
