Celestine Omin, 28, is a Nigerian software engineer who built his portfolio from the ground up by creating church websites for free. The engineer’s talents were spotted by various local startups and later hired by Andela, a company founded by Mark Zuckerberg and Priscilla Chan to help African programmers work with top tier US tech giants. Omin was granted passage to the US, where he was supposed to meet with Andela’s New York branch about an upcoming project. He says border agents didn’t believe he was a software engineer and that the test was only an excuse to deny him entry.
