It's the same term that was used for transitioning textile and other factory work to third world sweatshops.

Hiring internationally is just that. You might get someone for a bit cheaper (somewhere in the neighborhood of 20ish percent), but that's usually in exchange for the extra hassle of managing a remote team and dealing with timezone issues. You don't usually crank through these people every quarter, they're hired for the longterm (or, as longterm as anyone in a software job is hired for).

Both have their benefits. In my experience offshore teams are basically an army that you need to train and provide a lot of direction. It can be very frustrating but if you have code generators, Sonarqube, linters and they are only working on CRUD applications it sometimes works out. Whereas international hires are usually very competent because you personally selected them.

Speaking very broadly here, my impression is that those offshore development shops bidding for US contracts often don't have the greatest working conditions. Those talented enough to know their worth and find better options will do so if the opportunity presents itself, which could mean either applying for international positions on their own or immigrating to where the jobs are. Thus there's an outflow of talent away from those offshore companies.

Hiring internationally, you might have TZ and language issues but none of the other stuff. If you do your hiring right that is, you'll get somebody who actually wants to be part of the team and is product oriented.

It's mercenaries vs. paladins.

One thing that I have found with "offshore" hiring: The very best have _mostly_ migrated to high cost locations because they get a huge salary increase (far more than cost of living increase). There are _some_ exceptions where the candidate is very high skill, but needs to live in a developing country. Usually family or cultural reasons. However, they are very hard to find and harder to keep.

In comparison to hiring individuals internationally to work with an internal team.

In the first case the entire project is "offshore." In the second case only individual team members are not in the primary country.
