<p>Well after the post 9-11 backlash which was severely felt by the Arab commnity in the USA and how many were denied visas etc , your feelings are completely justified. However since this was simply 1 persron acting alone , it wont affect South Koreans too much. Visa Issues would continue like normal. In the first month following the shooting , maybe the South Korean community maybe a little insecure and things may be uncomfortable but after that it should all return to normal.</p>
