Hi folks, I have a doubt regarding financial related documents for visa interview. Is it necessary to get a CA certificate ? What exactly do I need to show to support my funds ? Like I have a FD of 45 lacs and a loan application of 20 lakhs. Should I just carry the FD statement and loan confirmation letter ? Would that be enough ? A lot of answers on Quora suggested not go for a CA certificate and instead summarise the funds on a paper. I am very confused, I'd really appreciate any inputs you can give me regarding this.
