Think of it this way - if they’d hire you, why wouldn’t they hire someone much cheaper. You can’t identify them from the outside, but your network can. If you want to try, try companies with heavy worldwide presence.
Americans are not necessarily expensive in this day and age. Maybe the ones in the big cities are, but international salaries are rising up to match. Plus, they might be happier with a lower salary in a lower cost of living, especially if the quality of life is boosted by weather/location/food/hot people into foreigners.
American salaries likely anchor high though, and you can probably still get a decent amount above locals for the same work.
Plus even if you were mid, you'd be mid for the upper tier market. That might still be better than an average market, and you might do well in a market that's facing a shortage. Keep an eye on HN to see which countries are investing massively in tech.
