Just submitted to Los Angeles Consulate and I was trying to add my tax documents (CA state income + federal) along with my bank statement but even after compressing many times the files were still way too big (if I kept compressing it the quality would be awful) so I submitted the application only with bank statement without the tax documents.

Can I submit them separately or just have to wait until they request it?

Will this delay my application if they ask for them later or should I be ok without them? My flight out date is Jan 12 so I'm hoping it won't push it back or delay too far from now.

Can anyone advise me on the right documents, requirements and process to follow for a study visa?

The college indicated that I can collect documents from them, can I do this application myself in person? What do I need to have in place? They have indicated that I need to have an address in Bangkok but I am currently in Korat. I will travel to Bangkok to complete the visa process. My entry visa expires on 6 August.

Thanks in advance
