就像上文小曹所說，你如果涉及到馬來西亞逾期逗留處理操作的話，可能需要以信函書面的形式去做一些關于你來龍去脈的解釋，尤其是當你得到了一個被拒絕入境后需要做上訴的時候可能更會用上，當然這個馬來西亞移民局自首解釋信肯定是需要全英文書寫的了（要主動解釋），以下是小曹關于他人解釋信函的一個樣本分享給大家，不懂的可以再問：

To The Immigration Department 

Putrajaya Malaysia 
Dear Sirs/Madams 

1.  Reasons for the Overstay  

2. The Appeal not to BAN me from visiting Malaysia again. 

My name is GAO xxxxx ，Age 23, Passport no: E30257476 Ref (Doc-1). I came into Malaysia on 09/07/2018 on a 30 days Visitor Visa. I enclose my airline boarding ticket in lieu of the entry stamp, Ref (Doc-2). I came to visit friends and long distance relatives for the first time. Enclosed is my Single Entry Visa Ref (Doc-3) 

Around 05/08/2018 my friends introduced me to a agent who told me that I can make an extension to my Visitor Pass for another 2 months.  I believe the agent as Malaysian visitors to China were allowed to extend another 2 months. For 2 months they did not give me back my passport saying that my extension is still under processing in Immigration Department. Around 02/11/2018, I managed to get back my passport without any extension pass inside. 

On 05/11/2018, I went direct to IMI Putrajaya to surrender myself for overstay. The officer told me to come in after 1 week for further instructions. I went back after 1 week to be informed that I have to bring a flight ticket within 7 days. I have ran out of funds by then and waited for my family to send me funds. On 30/11/2018, I went to the KLIA Airport to purchase a air ticket but I lost my passport there. 

Enclosed is a copy of the Police Report on the Lost of my Passport. Ref (Doc-4) dated 30/11/2018. 

Enclosed is a copy of the Travel Doc (Replacement Passport). Ref (Doc-5) 

Appeal for lesser Ban or NO Ban 

I wish to make an appeal to Immigration not to BAN me from coming into Malaysia to visit my friends and relatives again. There is no intention to overstay deliberately. The above circumstances have resulted me to overstay. 

Thank you Sirs/Madams for your kind consideration 

Yours Sincerely 

Gao xxx

要怎么說才好呢，基本上就是你認真書寫到了這封信，然后向移民局相關工作人員做遞交，至少你還有一線希望得到你想要的結果，但是如果你是什么都不做的話，可能人家就默認為你放棄解釋了，所以最壞的結果也就理所當然的砸在了你的頭上，所以小曹覺得我們能做的解釋就要盡量去做，總好過什么都不做所帶來的結果不是嗎？好了，大概就說到這，需要買關的可以聯絡喲，呵呵。
