Hi I have applied for US visa and got approved the same day but the online status showed refused for few hours and after that approved. and issued. I was not given any slip or documents. They took my passport and I was told that the passport will be back with visa stamp in few weeks. I got passport with visa stamp in less than a week. Why that refusal was for? Does it count as an actual refusal? and do i need to disclose in future application in Canada and for PR?
