How do I start writing a petition letter to the UNHCR asylum office in Nairobi, Kenya? The reason for my appeal is file changer to Nairobi Kenya I have serious health problems like asthma and high blood pressure.My illness is worse in countries where the weather is hot.So I find it very difficult to live in a hot country. I also kindly ask you to understand my health problems and transfer my file to Nairobi so that I can attend the UNHCR branch office in Nairobi.
