Police Clearance- can someone please clarify this for me

[mhaze 0]

in our police clearance, i was confused about the expiration date. i know its only valid for 6 months, however, when i read my moms police clearance, there were 2 dates showing, the first one is the top right corner and the 2nd is on bottom left where it said issued on.

i asked my mom about it and she said the date on the bottom left is the cedula. Which date should we start counting till the expiration the top right or bottom left?

Thank you.

For immigration purposes, background checks are good for one year despite any expiration date on the form.

Important: Police certificates expire after one year, unless the certificate was issued from your country of previous residence and you have not returned there since the police certificate was issued. If at the time of your interview the following three items are all true, you must bring a new police certificate to your visa interview:

You are more than 16 years old;
The police certificate submitted to NVC was obtained more than one year ago; and
You still live in the country that issued the certificate.

For country-specific guidelines on how to obtain a police certificate, review the Country Documents section at Reciprocity by Country.
