由于本人存款未满3个月导致拒签，出具了资金来源证明和银行证明也没有用，郁闷啊。由于时间紧急，所以只能让学校出具一个sponsorship letter。具体要求如下：
If your sponsor is certifying your maintenance
If your sponsor has an A rating, they can certify on the Certificate of Sponsorship that they will maintain and accommodate you up to the end of your first month of employment in the United Kingdom if required. Your sponsor may limit the amount of the undertaking but any limit must be at least £800. If your sponsor certifies maintenance, this must be confirmed on your Certificate of Sponsorship. If the sponsor is certifying maintenance for your dependants as well, you or your dependant must provide a letter from your A-rated sponsor, which can be posted, faxed or scanned and emailed to you or your dependant. This must be on official letter-headed paper or stationery of the organisation and signed by a senior official and must show your name; details of your dependants, your Certificate of Sponsorship reference number; the sponsor’s name and logo, and confirmation that the sponsor has certified the maintenance, and details of limiting the undertaking if appropriate. http://www.ukvisas.gov.uk/en/how ... lledworker#21988252
