Anonymous participant - So they are not going to search for your stuff on a webpage. You need to include everything you want them to see as pdf documents that you upload into the application.
Depends on the embassy that you are applying via, but most say you shouldn’t apply more than 2-3 months in advance. That being said, besides saying when you will go, the embassy nor immigration will know when you actually go and if you end up going later, that is fine. However, if on the application you said you are not going for 6 months, they might not review it any time soon
Your visa is valid for 5 years from date issued by the embassy, regardless of when you plan to travel. When you arrive, you receive a 180 day entry stamp and have to leave within 180 days
I think you misunderstood the request. While you are required to show 500K (which it sounds like you already have done), they now want proof of employment via pay slips and money entering your account (regardless of what account) matching your payslips. This is a completely different request, not related to the 500K and is probably a way for them to verify that you have actual employment
usually it is valid but you are still required to carry with you the expired passport. Not sure how it is handled when you don’t have the old passport anymore.
