Thank you for your enquiry.
You should be able to make an application under the 10year rule providing you meet the requirements. Periods of any overstaying of 28 days or less would usually be ignored.
Best of luck
Hopefully this shouldn't cause you any issue with your application.
It is not as simple as a yes or no answer. It will depend on the reasons for the refusal and whether the Home Office accepted your application was submitted in time and also whether the Home Office gave you the opportunity to resubmit your application the second time and you submitted it within any deadlines given.
Overstaying a visa is when your visa expires and you do nothing about it and more than 28days have pasted. If you applied before your visa expires and it is returned because it is invalid and you are given the opportunity to complete and you complete within the deadline given then you haven't overstayed even if your visa had expired because it was in the hands of the Home Office when it expired. But if you ignored all reasonable attempts by the Home Office to contact you to correct your invalid application and the Home Office returns your application and you did not make a further application then the Home Office will usually inform you. If you haven't been informed by the Home Office then hopefully you should be ok. I cannot give you a yes or no answer only the Home Office can.
I will give my final answer when you have rated
You will have to wait for the decision of your ilr application. The Home Office will say whether you have right of appeal. Y
That is great news for you.
