Clear Admit at the 2016 GMAC Conference

Two-time founder (marketing agency during undergrad, then a fintech post-graduation), ex-Kearney consulting, currently on the founding team of a boutique financial consulting firm. Based in Pakistan, 29. Forbes 30 Under 30 honoree. Undergrad from LUMS (top business school in Pakistan) with a 2.91 GPA, which I know is my main weakness.
Targeting HBS, Stanford, and MIT Sloan for R1. I'm aware these are reaches given my GPA. GRE is in progress, currently retaking to push into the 315 to 320 range with a strong quant score to offset the academic profile.
Post-MBA goal is to scale into senior operating or founder roles in fintech and financial services, building on my consulting and startup background.

GMAT/GRE waiver, realistically what are my chances? I have 4 major exercises and 1 deployment. The reason for the waiver is time constraints as I am currently deployed.

I'm a dentist from India exploring international MBA programs and would appreciate some advice from people who have either gone through a similar transition or have experience with MBA admissions and outcomes.

My long-term goal is to move into the healthcare/healthtech ecosystem, potentially in areas such as healthcare consulting, product management, healthcare strategy, or healthtech startups. I am particularly interested in leveraging my clinical background rather than moving into a completely unrelated field.

I'm currently evaluating MBA programs in Europe and Asia (Singapore, Japan, HongKong)

For context, I have a GMAT Focus score of 575 with 4 years of work ex within the clinical and corporate side of the healthcare sector
