I have attended my H1b visa interview on 21 Dec 2015 in Chennai consulate. The VO officer asked few questions and verified my I797 and passed back to me.Then she said my visa is approved and handed me a pamphlet to read when i am free. After a week of time i got mail saying my passport is ready to be picked up at the collection centre. However i got my passport without visa stamped along with 221g sheet saying my case is under administrative processing.
Is this 221G or normal processing that is done before every visa is issued? Does anyone know of any case where it has gone into 221G after the visa officer said that the visa is approved? I would greatly appreciate if anyone sheds some light on this.
