How Missouri Apostille Processing Works
Getting a Missouri document apostilled follows the same steps every time. Here's what happens when you bring yours to us:
1. Document review — We look over your document to confirm it's complete and ready for the Secretary of State. If something's missing, we'll flag it before anything gets filed.
2. Preparation — We get your document package ready for submission, including notarization where it's required.
3. State filing — We file with the Missouri Secretary of State. Standard processing runs 24–48 hours.
4. Return shipping — Your apostilled document ships back to you with tracking included, so you always know where it is.
Standard service is $190 for the first document and $100 for each additional document, with return shipping and tracking included.
How Federal Apostille Processing Works
For FBI background checks and other federal documents, filing goes through the U.S. Department of State. Here's what happens:
1. Document review — We review your federal document to confirm it's ready, and confirm your timeline after the review.
2. Preparation — We prepare your document package for the Department of State.
3. Federal filing — We handle the filing and follow it through to completion.
