I have been to the US,India and Canada. I also gave them travel history of my immediate family members (London, Greece USA South Africa, Dubai and Ghana) I made photocopies of their passport datapage as well as inward and outward immigration stamps, to prove that we always return to Nigeria after every visit
My dad’s company stood as a sponsor and I submitted the companies dollar account bank statement, particulars of directors, audit report proof of business activities(receipt and invoices), article of association, tax clearance, company profile, sponsorship letter signed and stamp by the CEO.
I gave them work ID’s of my siblings and dad, and explained the kind of job they do, to prove that my family members have vibrant careers and live in Nigeria and made them understand that family was very important to me, and told them to confirm from my passport of my return home during summer and Christmas holidays when I was studying for my undergrad in Ghana.
