Business Visa - B1

My B1 Visa experience was pretty cool..I work for a subsidiary of a US company and I was supposed to go to the parent company on a 3 month business visit..The parent company sent me the following documents which I used as my supporting documents: 1. A bank statement 2. An invitation letter 3. Company Registration records of both parent and subsidiary companies 4. A letter of representation by the parent companies Attorney ..I then attached the following as supporting document: 1. My pay slip ....The day of the interview was February, 3rd (2012) and my appointment time was 7.30 pm..So we all went through the usual process of biometric data collection etc till we were made to be in a queue for our interviews..When it was my turn, My interviewer was a pretty nice person..She asked me the following questions: 1. What was the name of my parent company? 2. What was the purpose of the trip? 3. My job role and description 4. How long I was going to spend on the trip 5. How much was my salary? 6. What does the company do? 7. Had I ever travelled outside the country? I hadnt 8. What school I attended? 9. What program/course I did at school? 10. What work does my father do? (I thought this was a weird question lol)..and then she said: YOUR VISA HAS BEEN APPROVED! Next she attached a slip with a number to the back of my passport and gave me the other half and asked me to come back to the embassy on the following Tuesday..The interview was on a friday.....The following Tuesday I went to the embassy and after about 15 minutes wait, I was called to receive my passport and the visa I was given was a B1/B2..(validity period) From: 6th February, 2012 - To: 2nd February, 2017 (5 yrs) , With No Annotations! lol....I'm so grateful to God and very happy! :-)..My flight date is coming up in 9 days (24th February, 2012) and I have my tickets and everything ready..so I'm now doing my preparation and packing :-)
