Hello Brett
Kindly note that possession of a residence permit in Latvia does not automatically provide the right to enter other EU countries. To gain this privilege, you must first obtain the status of "EU Permanent Resident".
To do so, you must provide proof of a stable income, sufficient for you and your familys maintenance. Further, you must have resided in an EU country for a minimum of 5 years, with annual leaves totalling less than 10 months.
Hope this piece of information might help you.
Regards
