Business Visa - B1

Background: I studied my MSc in France and BSc in UK and I worked in Switzerland for close to 2 years with big European Company before I moved to India in 2013 where I changed jobs quickly and till April 2016 I was almost with 4th employer in India (5 companies in 6 years). I am 30 years old single male. I have Canadian Permanent Residence since Sep 2017

I applied for B1 in April 2016 with my then employer. I was denied on 214b (was stammering as I was nervous). At that time my Salary was 14 LPA and experience of 6 years. I have changed my employer couple of time till April 2016 and I have worked with that employer for around 1 year 4 months when they applied for my B1.

Now coming to Today, same European company which hired me in Switzerland also hired me in India (I have been working since Nov 2016 with this company in India) and sent me 3-4 times to Europe (Italy, Switzerland, Netherlands, Denmark, Sweden). I have been personally Europe as well (France, Netherlands), Canada, Singapore, Hong Kong and Dubai.

I make close to 25 Lacs Per Annum now.

Typing, Typing, Typing, Typing, Typing (2-3 minutes) I thought she was looking reasons to reject me.

VO: We cannot approve your visa

What is the reason for her rejection, I wonder?

Salary? No I am def above average

Manager, still no one reports? Aren't they aware of Individual Contributor roles!

Travel History: Very high, Cannot see this as reason

Me being single? Yes may be!

Could Canada PR be the reason? Although nothing was asked about this!

Didn't have agenda for Conference or meetings, may be

No relatives or friends in US...I still ponder....I have got two rejections now one in April 2016 and another in Jan 2019...Now my company wants to apply again in Feb 2019....Wonder what they will do now!

My company is one of the biggest companies in World (hiring close to 50,000 people in US)
50,000 in Europe
100,000 in RoW
