Dragging up this old post to add some new information for those who are going to this right now:
Most important the "verklaring behoud Nederlanderschap" is now valid for 13 years!!!!!!! It is no longer the get out of jail card it was.
- Verklaring behoud Nederlanderschap can now be applied for "online" https://www.nederlandwereldwijd.nl is the latest site with info
- Passport renewing currently requires a checklist and a bunch of other documents again https://www.nederlandwereldwijd.nl is the latest site with current info.
- Certified true copy of your naturalization certificate is what you need to obtain from the USCIS and then you need to get an apostille from the US state department (whole thing took me about 3 months from calling USCIS to getting the papers back from the state department. Cost is around 25 bucks.
- marriage certificate (or divorce decree). State specific. in Virginia I ended up walking into the "office of vital records" 3 miles from my house and they printed it right away. Then I had to sent the whole thing to the State to get their apostille on it.
- Passport of Spouse (or ex spouse). Apparently a copy is enough these days. No need for certified birth certificates.
- Bewijs behoud Nederlanderschap was 30 euro and took 1 email, one payment (thank god I still have access to a Dutch bank account) and about 3 weeks.
- Passport renewal. Being able to even schedule an appointment can be a challenge. I was finally able to get one for 2 months out but it took weeks before one was even available.
