Dear Madam, Sir,

I am writing to express my concern regarding the prolonged processing time of my citizenship application, which was submitted on [Date] and received on [Date].
 
As of today, [Date], it has been [X] months since the submission of my application.

I understand that processing times may vary, but the extended delay is causing significant hardship for me.

Considering the standard processing times of [X] months and the impact this delay has on my life, I kindly request that my application be finalized within 30 days.

Failure to receive a decision within this timeframe may compel me to pursue legal action to expedite the process.

I would like to bring to your attention that I am prepared to file a Mandamus application in Federal Court if my application is not concluded within the specified 30-day period.

I sincerely hope that it will not be necessary to take legal action, and your prompt attention to this matter would be greatly appreciated.

If there are any additional documents or information required to expedite the processing of my application, please do not hesitate to inform me.

Thank you for your understanding in this matter. 
I look forward to a swift resolution to my application.

Yours sincerely,
[Your Full Name]  
[UCI / Application Number]
