The RFE had the below questions (don't remember exact wording):
Q1: H1B is for speciality occupation, for which a bachelors degree is a minimum requirement. Justify how your current position require a bachelors degree.
My comment: I asked the end customer manager. Bachelors degree was the minimum requirement for my position.
Q2. List out your daily roles at work. Justify how a bachelors degree is needed for each.
My comment: How many of us are actually doing anything that we learned in college?
Q3. The project duration is only for 1 year. Why did you ask for a 3 year extension?
My comment: We have been working with this customer for more than 8 years. They issue yearly project orders for that financial year. They don't issue PO for more than a year.
There were 2 more questions that were similar in nature to Q2. Even though my employer had a team of attorneys, they asked me prepare a response to these questions. I sent it to my employer, not sure if they modified it.
Got my visa approved 2 days after the RFE response reached USCIS (according to USCIS case status website).
Almost all my colleagues (I worked for an Indian company) received the same set of questions during their extension.
