I applied for a greencard 12 years ago via my sister (family 4). last may i was informed they were ready to process my visa, having completed the relevant paperwork to date soley without help, i received my interview date this morning for 24th August(So i must have been doing something right) I have an appointment for mine and both my daughters medicals on the 14th August and i have all the evidence requested in place. From what i can gather this is. pretty straight forward. My actual concern lies with the interview itself as i have no idea as to what questions they will ask me being that i am not entering via a spouse. I understand that some people take along more evidence than is actually required. I was wandering if i should take my Ba and PGCE certificates as additional evidence. My sister submitted the affidavite of support back in the states some time ago, so i am assuming that this is adequate enough in respect of financial support. I dont know how i managed to get to this stage without seeking help but after visiting this site for the first time today, i have read some very useful information in respect of medicals. if there is anyone out there that has attended an interview based on F4 grounds i would appreciate any advice you can pass on in respect of interview. Thanks
