As @Mr.Smile12 alluded to, even if you go and accrue “200 hours” over the course of a few weeks, that is not going to be seen as favorably as someone who gets a similar number of hours over the course of a year. Frankly it doesn’t matter what you put for your number of hours, there is going to be an assumption (true or not) that you spent a decent amount of those hours exploring the country you’re visiting and not necessarily delivering impactful care.
Bottom line, it’s fine. Do it if you would enjoy it. But unless you are going to craft a very specific message around how you want to practice global medicine (which you can’t do from a single international trip), this is not some crown jewel experience that will open doors to you. You should plan to get the same other experiences, including US based clinical experience, nonclinical volunteering, and (if it’s your thing) research. Any hours you get from this should be seen as a “bonus.”
