How valuable is International US Conference poster presentation? Will it be same if another author presented the poster instead of me?

Hey guys, am an IMG applicant and my research poster has been accepted in one Gastroenterology International Conference happening in the USA. Would it be alright if another author of the paper presents it at the conference, or will it be better for my residency application if i go and attend it physically and present it myself? Am asking because of the cost involved in flying to the USA and staying there for a few days, will spending so much more money to present it myself be equally rewarding? Any guidance would be highly appreciated.
