MBA or transfer for MS?

A brief about myself, just turned 24 and completed MA Eco from a non-target in India in the pandemic which had no tuition fees to save up on costs, and have another MA Accts & Finance from Heriot Watt University in Dubai, currently working at Crowe in their financial advisory. Realised the dream to work in M&A post my first year in MA Eco, and did not have relevant experience, but networked enough to land this job, for a full-time for 2 years.

The role is great and its been about a month and a half, and have got abundant experience which I never imagined that I would get in my situation. However, the deal activity in M&A is not as sophisticated in Dubai and based on the experiences and opportunities available outside, feel like I am missing out and its too late to do an MS to get into US and try for IB. 

My concern is do you think it to be sensible to finish this role, and try for a MS program at a target school after 2 years, or would it be better to try to land a role at some boutiques or BB here and then try for a top ranked MBA and do the shift then? I am crazy about M&A, have been putting the time and efforts in, but does not feel like I'm receiving the worth in this region, and might be better to do the same in US by getting a better degree abroad and get better exposure? 

Would appreciate any advice from people in similar situations or anyone experienced enough to put some sense into my thick skull?!
