Just a brief snippet of information I came across today: immigration lawyer Moon Sang-il said in a blog post on Monday (link in Korean) that the average time for renunciation of U.S. citizenship in Seoul is two to four months. His statement was in response to a question from an anonymous reader who just had his/her first appointment at the embassy. Presumably he means four months from first appointment to renunciation, rather than from first appointment to receipt of CLN. Still, that’s much faster than what’s been reported for some other countries.
This would roughly match the timeline which New Frontier Party political organiser (and former Southern California Korean American community leader) Chris Nam faced: he started the procedure to give up his U.S. citizenship in July 2011, and actually swore the oath of renunciation in September. I’m not sure when exactly he got his CLN, but the Federal Register only got around to publishing his name in last quarter’s suspiciously small list — almost a year after he set the process in motion.
