I’m currently a student at a US public university as a B.S. Neurobiology major (graduated HS in US after joining in 10th). I am trying to apply with no gap years, which I know is becoming the exception these days.

I’m currently on an international status, but there is a high chance I’ll get my Green Card (GC) before I turn 21. If that doesn't happen in time, I’ll be looking at the F1/J1 route. I’m still prepping as if I’m applying international. I am a dependent of my parents currently so I most likely cannot get a paid job on an L2 visa but there are some exceptions.
I fully understand the dip acceptance rates (especially for internationals). So, I’ll be applying broadly to MD-PhD, MD/MPH, and MD/DO programs. I am also able and willing to take out loans to fund my education if needed.

Questions:

Since I’m trying to go straight through, does the "no gap year" path mean I need to overload on upper-level courses to prove I can handle the PhD transition early? Or is a 4.0 in standard pre-reqs better than a 3.8 with a heavy grad-level load? Can I use course work to improve my knowledge so I can access more research and internships early on?
What benchmarks should be aiming for. I know a pub/award is the gold standard but how can I show commitment and trajectory with 3 years of undergrad? Based on what I saw, 2000 research, 500 clinical, 250 volunteering, 100 shadowing seems to be what most people do
What specific themes (personality/academic focus) should I portray in my essays or activities if any to show I’m ready?
Has anyone here made it through from a similar situation? Any tips?

Wold greatly appreciate any advice from even those who may have taken gap years or are domestic

TY!
