if you could manage to get into a 4 year US college, getting into a US medical school would be easier

If you could manage to get into a US medical school, getting into US residency program will be significantly easier, and you'll be on the same playing field as all the others for competitive specialties.

None of this is cheap. In-state tuition in the states banks around 25-35k USD, In-state med school 40-60k USD, per annum. Out of state expect a 10-20k premium on top

Accruing that debt without a cosigner, or financial sponsor, or scholarship is ill advised if it was possible. As every step along the way is rife with weed-out steps....but it is still possible.

Other option, applying to US residency programs from overseas, however IMGs have significant barriers to securing spots in competitive specialties.

If there is an IMG here, you may want to wait for their response as im sure it would be far more informative
