CR-1 and IR-1 Are the Same Visa With Different Clocks
Both categories are immigrant visas for the spouse of a US citizen. The distinction is duration of marriage at the point of entry to the United States.
A marriage of less than two years at entry produces a CR-1, where CR stands for conditional resident. Permanent residence is granted with a two-year condition attached, removed later by filing Form I-751. A marriage of two years or more at entry produces an IR-1, immediate relative, with residence granted unconditionally.
For document purposes this distinction changes almost nothing. The Thai civil records required are the same, the translation requirement is the same, and applicants frequently discover the category was determined by processing times rather than by anything they chose. A couple who filed while eighteen months married may well enter after the second anniversary.
The category may shift between filing and entry depending on how long processing takes. Prepare the document set on the assumption that requirements are identical, because for translation purposes they are.
The Marriage Certificate Is the Center of the File
A spouse visa rests on a legally valid marriage, and in a Thai case the document proving it is the marriage registration certificate, Kor Ror 3 (คร.3), issued by the district office where the marriage was registered. The related Kor Ror 2 is the registration record itself, and some posts ask for both.
This is the document where translation detail matters most, because it carries several elements that a rushed translation treats as background: the registration number, the registrar’s name and office, the date of registration as distinct from any ceremony date, and the witnesses. A translation covering the two spouses’ names and the date, while omitting the registration particulars, leaves out precisely what makes the certificate evidence of a registered marriage.
A religious or customary ceremony without district office registration does not create a legally registered Thai marriage. Couples occasionally arrive at the interview stage having held a substantial wedding and never completed the registration.
If you married outside Thailand
The marriage certificate then comes from the jurisdiction where you married, and if it is already in English it needs no translation. Thai documents about the spouses themselves — birth certificates, house registration, prior divorce records — are still Thai documents and still need translating. Marrying abroad removes one item from the list rather than the list itself.
The Rest of the Set
Birth certificates for both spouses
The Thai spouse’s Suti Bat (สูติบัตร) is standard. Older certificates are often handwritten and may reference district names that have since been reorganized, which is worth flagging when you send it for translation. The US spouse’s birth certificate, being in English, needs no translation.
Police clearance certificate
From the Royal Thai Police Criminal Records Division, for the interview stage. It is time-sensitive: obtained too early it may be treated as out of date, and there is no single published validity period — the interviewing post sets what it will accept. Applicants who have lived elsewhere for extended periods may need certificates from those countries too. The K-1 guide covers the timing question in more detail; it works the same way here.
House registration (ทะเบียนบ้าน, Tabian Baan)
Confirms address and household composition. In a spouse visa file it also carries relationship weight that it does not carry in a fiancé case, since a household record listing both spouses is evidence of shared residence. Which pages are needed depends on what the file is demonstrating; whatever pages are supplied must be translated in full, including all residents listed.
Divorce or death records, where a prior marriage existed
Either spouse having been married before means the file must show that marriage ended. In Thailand the divorce is recorded on the divorce register (Kor Ror 6) at the district office, and each party receives a divorce certificate (Kor Ror 7) as proof — the same register-and-certificate split as Kor Ror 2 and Kor Ror 3 for marriage. Supply the Kor Ror 7. Where the divorce was contested, the court judgment takes its place. Judgments run long and need translating completely, including the procedural sections. Where a former spouse died, the death certificate substitutes.
Children’s documents
Children immigrating alongside a parent under CR-2 or IR-2 need their own birth certificates translated, showing parentage. Where custody is shared, was determined by a court, or where adoption is involved, those orders belong in the file as well, and court documents again need translating in full rather than in summary.
Some Thai Documents May Already Be Acceptable in English
Worth checking before you pay to translate anything. The US Embassy Bangkok immigrant visa instructions state that non-English documents require a certified English translation, while civil registration documents issued directly in English by a Thai district office may not need a separate translation.
Many district offices will issue English-language versions of common civil records on request. Where that is available, obtaining the English original can be cheaper and faster than translating the Thai one. It is not universal, the offices vary in what they will produce, and the checklist issued for your case governs.
Before commissioning translations, ask whether the amphoe will issue the record in English. Then confirm against the checklist supplied for your case, since posts differ on what they will accept.
NVC Stage and Interview Stage
A spouse visa case passes through the National Visa Center before it reaches the embassy, and documents are uploaded there. A common question is whether the same translations serve both stages.
Generally yes. A certified translation does not expire; what can expire is the underlying document, most notably the police certificate. The practical consequence is that translation is worth doing once, properly, with hard copies retained, rather than repeated at each stage. Keep both the digital files and physical copies, since the interview itself is a paper occasion.
One Spelling Across the Whole File
Thai names can be romanized several defensible ways, and the passport has already chosen one. Every translated document should follow the passport spelling, including middle names.
Spouse visa files are especially exposed to this, because they contain documents about two people issued across decades by different offices, plus children’s records. Setting the spelling once and supplying it with the documents prevents a file where the same person appears under several names.
Requirements vary with each applicant’s history and with the interviewing post. Use the US Department of State family immigration instructions, the US Embassy Bangkok immigrant visa instructions, and the checklist supplied for your case. The translation requirement is at 8 CFR 103.2(b)(3). Nothing here is legal advice. Last checked 19 August 2026.
How We Handle Spouse Visa Document Sets
We have translated Thai marriage certificates and supporting civil records for spouse visa cases since 2008, including older handwritten birth certificates and full court judgments. Names, dates, place names and registration details are checked against the passport spelling you supply before delivery, each translation carries a signed certification statement, and hard copies can be collected at our Chit Lom office before a Bangkok interview or couriered elsewhere in Thailand.
