We just received confirmation that the I 824 application for our 20 year old son has been approved. Luckily our family circumstances mean that he can 'follow to join' us. Now he has to do his part at the US Embassy in London (after his medical of course). Does anyone have any idea what kind of questions he might face? I have had a search on the forum but there's not a great deal on this, unless I'm not searching correctly.

Has anyone else been through this? I'm just a panicky Mum, that's all. I don't want him to travel from Glasgow to London (at my expense of course) and not be prepared, or balls it up! Not that I think he would but, you know how it is.....
