I married my Samoan fiancee in 2005. Little did I know he was an overstayer. We thought it would be easy since we were married and all we needed was to file in papers. While the papers were lodged , I realised I was expecting. After three months , immigration authorities surprised us to tears. my husband was deported I screamed telling them that we had a child how could they do this. He said he would wait 5 years and then come. My life has turned upside down. I was told getting a lawyer is expensive and with no guarantee. NZIS do not want overstayers to use marriage as a convenience, so it is painfully hard. Do not marry an overstayer. I will update later.
