Amazing visa officer , always kept smiling. Never have any sign of authority. Made the procedure very calm.
Maybe it was something that didn't qualify us. But all I can say is , officers are humans. And they do have the conscience and knowledge.

But yes it's all in gods hands. Don't lie , don't fake papers and don't make stories. These officers are good people and trained. Don't play with their instincts or knowledge. Feel sad about the rejection. But it's alright. There's always a next time.

Always be true and be thankful to god. Best wishes
