Need help picking a college major

I'm a current international freshman at an Ivy, and I plan on working in IB in the future. That being said, I'm not sure what exactly to major in yet.

I applied as an engineering major and that's what I'm currently majoring in. My HS subjects were mainly sciences, so I'm good at it too. However, I feel like I should change my major to econ. I'd like to work in the US after I graduate and I feel like if I major in econ, I'd be taking a risk and putting all my eggs in one (IB) basket, so I feel engineering is a "safer" degree in that aspect, but please correct me if I'm wrong.

Alternatively, I also have the option of modifying my engineering major with econ (however, this is essentially identical to a minor in econ from what I understand, which I doubt is enough).

Could anyone please give me some advice on what to do? Thanks.
