Can I keep my second passport when applying for D visa?

The visa center's website states that you need to provide an original work certificate and other documents confirming your trip. Without them, there may be difficulties in obtaining the visa.

Some participants report that the consulate accepts reservations without issues but does not consider fake documents. It's better to provide real confirmations to avoid rejection.

There is an opinion that requirements may vary depending on the consulate. In some cases, ticket confirmation may not be required if other documents are provided.

If you have a second passport, you can keep it, but it's better to clarify with the consulate to avoid misunderstandings. Some participants did this and did not face issues.
