往往在所有签证申请的导引上，对于个人存款或资金证明都会有这样一个要求， quote：
‘the closing balance date must be no earlier than 31 days before the applicant made their application. If the applicant provides evidence of funds at a
later date, you must not consider a closing balance later than the date of application.’
关于DOA， 境内选择邮寄的话，是邮寄当天算DOA；
国内则是网上缴费的那天算作DOA。
我想问的是，关于境内申请面签的话，是哪一天算作date of application?
原文上说的是 ‘the date on which the application is accepted by a Premium Service Centre of the Home Office, where the application form is submitted in person’
所以是DOA是指当天去面签的那天算DOA呢，还是说网上成功缴费（400英镑）的那天算作DOA呢？
因为这两段时间中间有间隔差，所以针对所有想要进行续签的申请人们，应该会蛮重要的吧，比如spouse visa需要在签证到期前28天内 或 呆满30个月的前28天内 才能申请。
