If you have gcms note already, go through it and see d red flag they want to ask questions about. Are they asking for additional support documents? Go with as many as possible, check online there are possible questions to be asked and it goes from how you met your pattern till the present moment. It is important she knows all about you, my husband was asked about my work, address and name a few colleaguesMy wife has an interview scheduled for the 18th of next month, is there anyone here who did one recently that can give advice?
