From 1 September 2020, foreigners applying for visas to Latvia will be able to submit their visa applications to any of the six VFS Services centers located in Washington D.C., New York, Chicago, Houston, Los Angeles and San Francisco. Please note that due to local restrictions regarding the spread of the coronavirus (COVID-19), the visa center in San Francisco is currently not accepting applications.
The embassy’s cooperation with VFS Services ensures that applicants can now submit visa applications to a VFS Services center after reserving their desired time slot. Once submitted, the documents are then sent to the Embassy of Latvia to the USA (Washington, D.C.) for deliberation. The visa centers offer visitors various services that make the visa application process more convenient, including gathering biometric data (finger prints), photography for the visa photo, consultations about the necessary documents, electronic visa application forms, copying of documents, scanning of photographs, insurance completion, and passport delivery to the home address.
