I was full time graduate student registered even in summer. I have submitted my transcripts, attestation from university and another attestation from my supervisor that I have worked in his research laboratory full time.Msafiri said:As a student you don't have to show up at school/ college/ university for a significant portion of the year. What was your actual total attendance number of days that could be proven? Further how do you prove attendance at your institution? Did you work during your vacation? Only full time work can close this line of inquiry off.
