Hi there. i just completed the visa process. so listen up. and no, u can only apply like a month or so before u're due to enter the UK.
u need the following documents to process the application and you have to make photocopies of them all except for number (4)
1) passport, current and expired
2) original educational certs
3) birth cert
4) passport size photo
5) father & mother's birth cert
6) pay the bank $20 to get them to issue you a bank statement showing proof of funds for 28 consecutive days
7) your CAS which is issued by the uni tat has accepted you
1) complete the online form here
http://www.vfs-uk-sg.com/applying.aspx This is known as the VAF9 form.
2) print it out
3) complete the checklist on VFS as well
4) there is another form to fill up as well. the VFS site will guide u.
5) schedule your appointment here. best to get the first slot in the morning. cos the wait is short, like 10 mins and then u'll leave the place in like 20 mins.

1) the visa office is located in 138 Robinson Rd on the 7th floor. the building name is The Corporate Office. it is situated beside State Bank of India. go to google maps.
2) they offer a super cool service at an additional charge of $3. they'll sms u immediately once u apply for the visa at their office, once they dispatch your application to KL and then once the visa is approved. definitely worth it!
procedures are bound to change so make sure u're in the know of such developments. and remember, the singapore office does not have the power to issue u the visa. they merely dispatch it to the UK office in KL. so if u forget to bring a document but choose instead the file the application, don't blame the SG staff for the rejection. they're just the middlemen although all the staff there are ladies, apart from the security personnel. LOL! but yeah. the onus is on you to ensure you have all the essential documents.
Good luck and all the best!
