Hi, don't don't ever think of coming down for that interview, if you can't spend more than six 6 months here, l mean in Africa. I'm in the same shit and still waiting for my visa, although l passed everything, i.e the PPR. Lost my job, lost my apartment and my credit cards are messed up and my car loan too.
On my interview VO told me l shouldn't have come but could have fought and request for my file to be transferred to USA. Do come, l repeat it is going to take you more than 6 months to get your visa
