A Spouse Visa extension, also known as a Spouse Visa renewal or FLR(M) (Further Leave to Remain as a Partner) application, is a process that allows individuals in the UK on a Spouse Visa to extend their stay and continue living with their partner.

To be eligible for a Spouse Visa extension, you generally need to meet the following requirements:

1. Relationship eligibility: You must still be in a genuine and subsisting marriage or civil partnership with your partner who is a UK resident or British citizen.
2. Financial requirement: You need to meet the financial threshold, which typically involves demonstrating that your sponsor meets the minimum income requirement or alternative financial criteria.
3. Accommodation: You must have suitable accommodation available for you and your partner in the UK that meets the Home Office's standards.
4. English language requirement: In most cases, you are exempt from meeting the English language requirement when applying for a Spouse Visa extension. However, it may be required if you are also applying for settlement (Indefinite Leave to Remain) at the same time.

The application process for a Spouse Visa extension typically involves completing an online application form, providing supporting documents, attending a biometric appointment, and paying the applicable fees. It is essential to ensure that you apply before your current visa expires, as overstaying can have severe consequences.

It's important to consult the official UK government website or seek advice from immigration lawyers or advisors who specialize in UK immigration law for accurate and up-to-date information regarding Spouse Visa extensions. They can provide personalized guidance based on your specific circumstances and help you navigate the application process successfully.
