(2) The leave is extended by virtue of this section during any period when - (a) the application for variation is neither decided nor withdrawn, ... (3) Leave extended by virtue of this section shall lapse if the applicant leaves the United Kingdom. (4) A person may not make an application for variation of his leave to enter or remain in the United Kingdom while that leave is extended by virtue of this section. (5) But subsection (4) does not prevent the variation of the application mentioned in subsection (1)(a).

“… any specified fee in connection with the application or claim must be paid in accordance with the method specified in the application form, separate payment form and/or related guidance notes, as applicable,” (rule 34A(ii)). Rule 34C provided: “Where an application or claim in connection with immigration for which an application form is specified does not comply with the requirements in paragraph 34A, such application or claim will be invalid and will not be considered.”
“Consequences of failing to pay the specified fee “37. Where an application to which these Regulations refer is to be accompanied by a specified fee, the application is not validly made unless it has been accompanied by that fee.”

“First, at the point at which the application is made, neither the Secretary of State nor the applicant will know for sure whether or not their application is valid. Applications may be made in good faith and believed to be valid, yet be invalid.

Second, the previous view that section 3C leave was not triggered by an invalid application has become very complex and difficult to understand both for applicants and caseworkers, giving rise to uncertainty in an area where it is important to be able to readily work out whether a person has had their leave extended pursuant to section 3C or not. Third, the previous view that section 3C leave was not triggered by an invalid application has become increasingly difficult in practice where the requirements for validity can arise after the application is made: for example the need to enrol biometric information.
