Will publishing a first author paper in ICECE2020 conference help me when applying for a PhD admission in the USA?
I suggest that you take every opportunity open to you to do research and publish it. It will never hurt unless you publish in predatory venues.
The university sponsoring this conference is reputable (and has a long history). The conference is in their main line of interest. I don't think you should have any qualms about submitting to such a conference.
While it might be a bit &quot;better&quot; to publish via a conference in EU, say, or US, it is probably financially impossible. Take advantage of all opportunities as you start on what you hope is a long career. Small first steps can be positive steps.
People elsewhere will understand these things in evaluating your work.
