No time for a proper post on this new case from the tribunal, NA & Others (Tier 1 Post-Study Work-funds)  UKAIT 00025, so I’ll just paste in the headnote, which speaks for itself:
i. The new-style Immigration Rules governing Tier 1 (Post Study Work) contain a Maintenance (Funds) requirement in mandatory terms that admit of no discretion and make no allowance for sickness or other mitigating circumstances.
ii. The effect of para 245Z (e), read together with Appendix C of the Immigration Rules and closely related parts of the Policy Guidance dealing with Tier 1 (Post-Study) Work, is that, to qualify, an (in-country) applicant must show he or she held £800 or over for each and every day of the period of three months immediately preceding the date of application.
iii. This requirement, however, is relaxed for those who applied before 1 November 2008. Under transitional provisions they were only required to provide a bank statement showing a closing balance of £800 or over bearing a date anywhere within the period of one month immediately preceding the date of application.
iv. The requisite amount of £800 or over can be shown in the form of a personal or joint account and may be shown in the form of personal savings held in overseas accounts.
v. Because the relevant provisions require applicants to show that they had the requisite amount of £800 during a three-month period of time immediately before their application, it is not possible to apply s.85(4) of the Nationality, Immigration and Asylum Act 2002 so as to enable them to succeed on appeal by proving they had the requisite funds for a period of time (wholly or partly) subsequent to the date of application.
vi. However, until s.85A of the 2002 Act is brought into force (subsection 85(4)(a) of which stipulates that in respect of appeals in Points Based System cases the Tribunal may consider evidence adduced by the appellant only if it was submitted at the time of applying), it remains possible for appellants to satisfy the requirements of para 245Z(e) by providing on appeal evidence in specified form showing that they had £800 or over in personal savings for the period of three months immediately prior to the date of application.
