I am planning to visit Saint-Petersburg for two consecutive weekends and if possible I would like to do so using their new E-Visa system since it's free and quick to use.
I know that an E-Visa is valid for 30 days and that they're single entry only. Also I've read that they cannot be extended or converted into a multi-entry version.
What I cannot find any information about is whether I can apply for a second (or more) E-Visa within the validity period of a pre-existing one with a chance of it to be issued.
Can I use the E-Visa system for this or should I apply for a regular one?
