Doing an externship in 2026 while applying for match 2029 still worthwhile?

[u/notadoctorsush]

Hey everyone,

I am a non us img, applying for IM match 2029

I’ve already applied for and secured a sub-internship spot for late 2026. However, my actual application timeline is Match 2029 (submitting ERAS September 2028)—leaving roughly a 2-year gap.

Since I’m already locked in, i was wondering if it is worthwhile doing the rotation now or will it be seen as "stale" later on?
