Dear M Thorp,
Re: Application for Permission to Stay in the United Kingdom under the Graduate Route
We are writing in response to your letter requesting further information regarding our
application for permission to stay in the United Kingdom under the Graduate Route.
At the time of our application, we were living at the same address. However, due to the end
of our rental contract, we had to move out. Unfortunately, we were unable to find suitable
joint accommodation immediately and had to move into separate single accommodations.
Consequently, Sandhu updated his new address, but Praseedha did not, hence there may be
a discrepancy in our addresses.
To demonstrate the subsistence of our relationship, we are submitting an insurance policy
document that lists Praseedha as the beneficiary of Sandhu's policy. This policy remains
active, and we continue to make regular payments on it, underscoring our ongoing
commitment and relationship.
We trust this explanation and the additional documentation provided clarify our situation.
Should you require any further details or additional documents, please do not hesitate to
contact us.
Thank you for your understanding and consideration.
Yours sincerely,
Praseedha Suresh
