I read on the Immihelp site that after Feb 1st 2010 online form DS-160 should be used, however on the link I got from the US Embassy in London it said to use DS156/DS156K. The petition was approved on Feb 26th and the letter from the US Embassy dated March 19th. Which is correct? I can't see the US Embassy site being wrong but at the same time the Immihelp site has been correct up until now.
