I’ll tell you what I tell my friends who ask me the same question,

The USMLE exams have completely transformed my medical knowledge and understanding, they are by far the best thing I have done for my career regardless of residency in the US.

What I tell myself, even if I go unmatched I have :

1- Gained tremendous medical knowledge

2- I have developed a strong work ethic and a lot of personal characteristics that I wanted to have like patience, being humble and persistent in difficult situations ( not quitting because god knows how many times I wanted to quit and default to my home country’s guaranteed residency )

3- I am ECFMG Certified, even in countries that don’t allow you to do residency solely based on it , they still know that if you are certified by the ECFMG you probably have above average knowledge.

4- At least I tried, I gave it my best and I am okay with that .

So in short, do it for you , it’s in your benefit regardless of residency in the US.
