NOTICE: The U.S. Embassy Bangkok and U.S. Consulate General Chiang Mai no longer provide the income affidavit. We will not notarize previous versions of the income affidavit. For more information, please refer to our Fact Sheet (PDF 266KB) and Frequently Asked Questions (PDF 419KB).
U.S. Consular Officers may provide specific notarial services authorized by relevant U.S. law and Department of State policy for all U.S. citizens. In addition, they can provide services for any person regardless of nationality so long as the document being notarized is required for use within the jurisdiction of the United States and is authorized by relevant U.S. law.
For detailed information about Notarial and Authentication Services of U.S. Consular Officers Abroad please visit the U.S. State Department’s official website.
Services we CANNOT provide:
U.S. law precludes the provision of notarial services in certain cases. Among others, Notarizing Officers cannot provide notarial services in connection with:
- Authentication, certification, or certified copies of public documents issued in the United States such as birth, residency, marriage, divorce, and death certificates; commercial records, driver’s license, and other credentials. Such documents must be authenticated in the United States for use overseas; for additional details, please visit the Department of State’s Notarial and Authentication Services or the Office of Authentication, or call +1 202-485-8000. Please visit the National Center for Health Statistics webpage Where to Write for Vital Records for state specific information on how to request copies of vital records.
- Academic credentials, transcripts or degrees: Contact the educational institution which issued the document. For further information visit the Department of State’s website Authentication of American Academic Credentials for Use Abroad.
- Certified true copies of non-U.S. documents, such as Thai birth certificates
- U.S. Apostilles: Information on Apostilles can be found on the Department of State webpage Judicial Assistance – Notarial and Authentication (Apostille).
- Signature or Medallion guarantees: A Medallion Signature Guarantee is not a notarial service, but rather a special procedure related to securities, which can only be performed by an authorized representative of a financial institution participating in a medallion program approved by the U.S. Securities and Exchange Commission (SEC).
- Statements beyond the Consular Officer’s knowledge: e.g. that the document satisfies a specific legal requirement, that a person is the spouse of another, or an individual is an employee of a certain business or corporation.
Services we CAN provide:
Oftentimes the Thai government requests the U.S. Embassy or Consulate General Chiang Mai “certify” documents listed under “services we cannot provide.” Please note the Embassy and Consulate CAN notarize an affidavit which may or may not satisfy the Thai requirement for “certification.”
An affidavit is a sworn statement of facts, made voluntarily, and confirmed by the oath or affirmation of the person making it. Please note the Embassy and Consulate assume no responsibility for the veracity of the representations that appear in the affidavit. Only the identity of the individual making the statement is validated.
The following affidavit templates are available for your convenience. It is prudent to confirm in advance if the end recipient will accept an affidavit.
- Blank Affidavit (Attestation of various types of requested information)
- Marriage Affidavit (Attestation of “single status” in order to be married in Thailand)
Acknowledgement of signature
An Acknowledgement of signature verifies a particular person signed a given document such as a deed or bill of sale. We can notarize only the signatures of those who are present to sign in front of a Notarizing Officer. If you are signing on behalf of a corporation, LLC, etc., you are required to provide proof that you are authorized to sign on behalf of the organization.
Power of Attorney
A power of attorney allows you to designate someone to take legal action on your behalf, such as authorizing someone to buy or sell a property in the United States in your name while you are abroad. You can use our blank Power of Attorney or bring your own drafted one. If you are signing on behalf of a corporation, LLC, etc., you are required to provide proof that you are authorized to sign on behalf of the organization.
Certified true copies of U.S. passports
Certified true copies of original documents and foreign passports for use with Social Security applications when requested by FBU Manila
Form DS-3053 Statement of Consent for issuance of a U.S. passport to a minor (No fee required)
Certified true copies of a foreign passport for use with Individual Taxpayer Identification Number (ITIN) applications.
- Individual Taxpayer Identification Number (ITIN) Applications:
The IRS is implementing significant changes made to the ITIN program under the PATH Act of 2015. The new law means that any ITIN not used on a federal tax return at least once in the last three years will no longer be valid as of January 1, 2017 for use on a tax return unless the taxpayer renews the ITIN. In addition, all ITINs issued prior to 2013 will begin to expire this year and taxpayers will need to renew them. The first pre-2013 ITINs that will expire are those with middle digits of 78 and 79 (Example: 9XX-78-XXXX). The renewal period for these ITINs began October 1, 2016. The IRS began to mail letters to this group of taxpayers in August to inform them of the need to renew their ITINs in order to file a tax return, and explain the renewal steps. The IRS will announce the schedule for expiration and renewal of ITINs that do not have middle digits of 78 and 79 at a future date. If taxpayers have an expired ITIN, not renewed before filing a tax return next year, they might face a refund delay and be ineligible for certain tax credits, such as the Child Tax Credit and the American Opportunity Tax Credit, until they renew the ITIN. More information is available on the ITIN page at IRS.gov.
Authentication or Legalization of Royal Thai Government Officials’ Signatures
Authentications certify the official seal, signature and/ or authority of foreign officials who perform an official act with regard to a document that is to be used in the United States. The U.S. Embassy may authenticate documents that bear the seal of the Ministry of Foreign Affairs provided their signature is on file with this office. A Consular Authentication does not attest to the authenticity of the contents of a document but merely to the seal and signature of the issuing Thai government official.
Only the individual(s) SIGNING the document(s) should schedule an appointment and appear. American Citizen Services has limited appointment availability. Individuals who are not required to sign should not schedule an appointment as it would take the appointment away from another person who may need it. Minor children may accompany a guardian, however, this is not recommended as the waiting area is small and unaccommodating.
If your document requires the presence of witnesses, you must supply these witnesses and each witness MUST have their own scheduled appointment. Witnesses must bring their valid government-issued photo ID. Consular staff CANNOT act as witnesses.
Please print, organize and complete the appropriate notary form before your appointment. There are no public printing or copying services at the Embassy and Consulate. If you do not have access to the necessary technology, you may obtain a blank copy of an affidavit in the waiting room on your appointment date. Use of the blank version will lengthen your check-in time.
In order to receive notarial services from the Consular Section you must:
- Understand your document. Consular staff cannot explain the contents to you;
- Complete the document with the appropriate names, places, and dates before you arrive (but do not sign it; you must sign in front of a Notarizing Officer);
- Include all pages, information and accompanying documents;
- Organize all pages in order and the page(s) that requires the notary seal must be clearly flagged on the edge of the document;
- Ensure name of the individual signing the document matches the name on the presented identification (i.e., passport or other government issued ID);
- If you are signing on behalf of a corporation, LLC, etc., you must bring proof that you are authorized to sign on behalf of the organization; e.g. business card and/or articles of incorporation etc.
- If your document requires witnesses, please ensure they each have a separate scheduled appointment and appear with a valid government issued photo ID;
- Do not sign your document until requested to do so by a Consular Officer.
Refusal of Notarial Services
Please be aware that a consular officer may refuse any notary service when:
- The document will be used in transactions that may be prohibited by U.S. law, treaty or foreign law;
- The host country does not authorize the performance of the service;
- The document is blank or incomplete;
- The officer believes that the document is suspicious, potentially illegal, or detrimental to the best interests of the United States;
- The officer does not understand the document, due to language or any other reason;
- The officer believes the customer does not understand the document or is acting under duress;
- The officer providing the notarial service has a disqualifying interest;
- Invalid, inadequate or insufficient proof of identification is presented, or proof of a corporate title or position is lacking or inadequate.
Refunds are NOT provided when a notary is refused. Customers must ensure they are in compliance with all of the above listed prerequisites.
Prepare for your appointment:
On the date of your appointment please bring with you:
- The unsigned, completed, and clearly flagged/organized document(s) you need notarized;
- Your valid government-issued photo ID; (Note: If your document references a specific form of ID you are required to present it at your appointment. A copy of the ID will not be accepted)
- One photocopy of the bio-data page of the government-issued photo ID you will present with your document;
- The appropriate fee of $50 PER NOTARY SEAL, payable in cash (USD or THB) or by credit card;
- Your (and your witnesses) printed appointment confirmation page(s).
Please be prepared to spend at least one-half hour to two hours at the embassy. Wait times are dependent upon the amount of notaries needed by each customer. ACS can notarize multiple documents during one scheduled appointment.
