After you collect the financial evidence in Step 4, and supporting documents in Step 5, you must submit all of these items in ONE package to NVC. Your case may be significantly delayed if you don't submit all of your documents at the same time.
IMPORTANT: Do not send your original passport or original civil documents such as birth, and marriage certificates. Instead, submit a photocopy of these documents to NVC. However, you must bring these original documents to your visa interview. This is true no matter what method you use to submit documents to NVC.
There are three ways to submit documents to NVC. The method you use depends on where you are interviewing. Look at your NVC case number and match it to the method below to find out how to submit your documents to NVC.
