Please help me my visa got approved on 2 June 2014, but on 28 June i got to know that my I-20 is cancelled due to my English proficiency. they told me that they will sent a new I-20 with different sevis number for next year may 2015. however i don’t know what will happen to my visa it will be valid or not if i wait till 11 months here.
