He testified as an expert for Respondent. Kempster opined that the purpose of the Affidavit of Support is to show that the person preparing the form is able to support the person applying for resident status. Based on the many immigration cases he has handled, Kempster is of the opinion that the term "current address" on the form does not necessarily refer to a residential address but to a place where the immigrant can be contacted or receives mail. Kempster also relied on the Black's Law Dictionary definition of address as a place where a person receives mail. In Kempster's experience, immigration officials do not rely on the Affidavit of Support to establish where the immigrant resides. On cross-examination, Kempster testified that he has seen the "current address" section of the form used for both residence address and mailing address. (Tr. 254, 259, 261, 263, 269, 285).
