Hi I appeared for a J2 visa interview on 27th July 2012 at the US embassy in Seoul,South korea.My husband is already in the US with a J1 visa since April 2012. As my PhD defense was due on May 2012, i did not move with him and applied separately and am planning to move in Aug. However, the VO retained my passport, gave me a green 221g form and asked a couple of documents by email. To note that my husband also went through 221g AP during his application time. I wonder if I am applying as his dependents with no intention to work in the US during my stay why am I being subjected to 221g? They have asked for sponsor letter from US...isn't the DS-2019 form issued by the university confirming sponsorship? I am very worried, please can u tell me how long this process will take?My student visa in south korea will expire in Aug and hence very very worried.Thanks in advance.
