Online app. and supporting documents

Hello,

I've posted here before and got very helpful advices, and I would appreciate your help once more.

1st question is:
Does the online application requires attaching or somehow online submitting a copy of the supporting documents, or am i only required to submit them when I attend the appointment at the visa centre? I am asking because there is one document that might take me a while to obtain, and i don't want to wait with the online application until I have it. If i have it by the time I attend my appointment, is that enough?

2nd question:
I know that i can only apply for tier 4 visa 3 months before my course starts, but does this time frame refer to the online application or to the appointment? I mean, can i apply online earlier and schedule the appointment to 3 months before the course start?

thanks for reading!

You can't attach any documents on your online application. You have to take all the original documents with you when you will go for the interview or you have to submit it before if they ask for it (please check your country's British High Commission's website).

As far as I know when you will make the online application from that day they will count 3 months before your course start date. Not when you have request for the appointment.

Thanks for your answer shaq, it was very helpful.
