My father is Assistant Research Scientist/Principal in Sardarkrushinagar Dantiwada Agriculture University.
My parents applied for US B1/B2 in April 2014. My mother got visa for 10 years, but visa office give 221G to my father and asked him to submit some documents in email for administration process.
In 221G, they asked for all research he did during his job, when he collect those data, it was more then 1500 pages. I collect only abstract from those papers or theses and it was around 90 pages.
He submitted this in email and after 2 weeks, he got mail to submit passport to VFS office. He submitted passport, and when we got passport, he had visa for 1 year only.
My parents came to US in December 2014 and leave US in Feb 2015.
In May 2015, my father's visa was expired, he has to visit US in next year. We thought to apply for visa again.
My mother had visa for 10 years, and father only has to go for visa again. First time, he choose English as interview language. Second time he don't want to take any risk and choose Gujarati for interview language. (We thought he might be not understand visa officer question due to pronunciation and give wrong answer, and got 221G). When he went for visa, he had all the documents which they asked last time in 221G. Visa officer again asked same question, like, are you going for any conference, or to attend any meeting, or to attend any college guest lecture, my father replied no. He told, my son is in US and I am going to meet him. Again visa office gave him 221G and asked to submit same documents he submitted last time. He has those documents, and he ask visa office to check those documents which they asked in 221G. Visa office told, please submit in email only, he could not check those documents now.
He submitted documents withing 2 days, because he had all documents ready. We were expecting, he should get 10 years visa because, he already visited once and came back to India in time.
Bad luck for us, he got visa for 1 year only. He came to US in March 2016 and will return in May 2016.
My questions are:
Is he belongs to special category due to his designation and got 1 year visa every time?
If he apply after his retirement (June 2016), is there any chance, he will get 10 years visa?
OR We have to apply before he has to come, so he can stay at least 6 month in US.
