Currently, there is not any investment visa for your amount. There are other types of visas, like the working visa that you could get if a Panamanian corporation sponsors you.
How can I obtain a Panama resident permit with a small investment?
I’m from Nigeria and have $5,000 to make as an investment in Panama. I know my country is not one of Friendly Nations, so I can't get a visa that way, but are there other options with my investment amount?
There are several residency-by-investment options, starting from a minimal investment of $80,000 on reforested land to $160,000 into your own business and, finally, investing $300,000 in real estate in Panama. These will also qualify you to acquire permanent residency in Panama.
Panama residency-by-investment options start at $80,000 with the reforestation visa. Other residency options without the need of investments are the professional's visa, the worker's visa and the student visa.
