Hello,
I am applying for my ILR. I just went through the guideline for UKVI new visa application process. It doesn't have guideline for standard ILR application submission.
Could anyone please help me to understand how to make the application and document submission for standard spouse ILR application? Can we send the documents through post?
Thanks
