If you are in the UK as a spouse of a settled person (i.e. a British citizen or someone with permanent residence status), and you meet the financial requirements, you can apply for ILR after 5 years.
However, if you do not meet financial requirements, you will be eligible to apply for ILR after 10 years of continuous stay in the UK.
At the moment, the threshold to meet the financial requirement is that your settled spouse  should be earning at least £18,600. Please note that this financial threshold increases as the number of dependents in your application increases.
For a detailed assessment of making an ILR application, contact our office and meet with an expert immigration lawyer.
For postal applications, the timeframe for a decision is between  3 – 6 months.
There is an option to make an appointment for a same-day decision in some specific instances.
