24 year old starting from the bottom

Hello WSO.

My Background:
-Born in a SEA country and moved to the US 4 years ago immediately after graduating from a local uni with a degree in Business
-I just got my permanent resident card a few months ago (got married)
-I was doing odd jobs these past 4 years. The most relevant work experience I did was doing bookkeeping for a real estate investor

I want to be involved in high finance in the long run (hopefully I get there before I turn 30), i.e., IB & corporate development and then eventually do consulting. I know that it is a long shot given that came from an unknown target school in Asia and I don’t have relevant work experience. but I'm willing to grind my way there.

I know that I definitely need to go back to school to do either an MSF or shoot for an MBA (maybe if I land a decent BO role). I’ve been reading my college Finance textbooks during my free time. I’m also in the process of completing the WallStreetPrep Premium Package in Financial modeling. My current goal right now is to get into a finance-related job while I’m working on getting a high gmat score.

My questions are:
1. Where do I go from here?
2. What entry level position should I look into getting before I get an MSF
3. Is it possible to get a position at this point that will enable me to lateral to an IB job?
