According to the dv website a police record needs to meet 3 criteria.
What Does the Applicant Submit
The applicant must submit police certificates that meet the following guidelines. The police certificate must:
- Cover the entire period of the applicant's residence in that area.
- Be issued by the appropriate police authority.
- Include all arrests, the reason for the arrest(s), and the disposition of each case of which there is a record.
While some COs may put you on AP for a slightly older police record, I would like to assume that as long as the police record covers the entire period of your stay you should be fine. I am not arguing or misleading. In fact my Canadian records are from February and interview is likely in September. I will let you guys know if there will be an issue. As well, I will write to US Embassy Nairobi who are very responsive and clarify the same. I speak only for Nairobi cases as I think they're a little more lenient than other African counterparts.
