The AI checks your answers before you download

12 checks built for this form, so a wrong date or a missing answer is caught before anyone else sees it.

NVC Case Number Format Validation

This check ensures the 'NVC Case Number' follows the standard format, which is typically a combination of letters and numbers (e.g., 3 letters followed by 10 digits). This is critical for correctly identifying and routing the case within the system. If the format is incorrect, the form submission should be rejected with a message guiding the user to enter a valid case number.

Principal Applicant Exclusive Selection

This validation verifies that the user has selected either 'Yes (Principal Applicant)' or 'No (Not Principal Applicant)', but not both. These options are mutually exclusive and one must be chosen to determine the applicant's status. A failure would occur if neither or both are selected, prompting the user to make a single, valid choice.

Conditional Relationship to Principal Applicant

This check ensures that if the user selects 'No (Not Principal Applicant)', the 'Relationship to Principal Applicant' field must be filled out. This information is essential for understanding the case structure and the applicant's connection to the primary beneficiary. If the condition is met but the relationship field is empty, an error should be displayed requiring the user to provide this information.

Applicant Full Name Completeness

This validation confirms that the 'Passport Name - Last (Surname)' and 'Passport Name - First (Given)' fields are not empty. A full name is a fundamental identifier for the applicant and is required for all official documentation and processing. Failure to provide a first and last name would prevent the form from being submitted.

Date of Birth Logical and Format Check

This check validates that the 'Date of Birth' is a real, valid date and that it is in the past. It prevents impossible dates (e.g., February 30) and future dates, which are logically incorrect for a date of birth. This ensures data accuracy for identity verification and eligibility determination; an invalid entry would trigger an error message.

Email Address Format Validation

This check verifies that the value entered in the 'Email Address' field conforms to a standard email format (e.g., '[email protected]'). A valid email is crucial for communication with the applicant regarding their case status and any required actions. If the format is invalid, the system should prompt the user to correct it before proceeding.

Common Mistakes in Completing DS-234

The ones the AI is built to catch.

Name Does Not Match Passport Exactly
Applicants often enter a nickname, a shortened version of their name, or omit their middle name, failing to match their passport exactly. This discrepancy can cause significant processing delays or rejection as identity verification is critical. To avoid this, meticulously copy your full name from your passport, ensuring every part matches perfectly. AI-powered tools like Instafill.ai can help prevent this by saving your official name and auto-filling it correctly across documents.
Incorrect NVC or SIV Case Number
Applicants frequently mistype the long and complex National Visa Center (NVC) or Special Immigrant Visa (SIV) case numbers due to transcription errors. An incorrect number can cause the application to be misfiled or unlinked from the primary file, halting all progress and causing major delays. Always copy the number directly from official correspondence and double-check it character by character before submission.
Inconsistent Answers in Conditional Sections
The form has many sections that depend on a 'Yes/No' answer, such as listing family members. A common error is to check 'Yes' but leave the required details blank, or to check 'No' but fill in the details anyway. This creates confusion and requires clarification, delaying the case. To prevent this, carefully read the instructions for each section; if you answer 'Yes,' ensure all corresponding fields are completed.
Miscalculating the 'Case Size'
Applicants often misinterpret the 'Case Size' field by forgetting to include themselves (the principal applicant) in the total or omitting other family members applying with them. This mistake can lead to logistical issues and delays in processing derivative visas for the uncounted individuals. To avoid this, remember to count yourself plus every single family member who is applying for a visa under the same case.
Using a P.O. Box for Physical Address
Applicants sometimes provide a P.O. Box instead of the required 'Physical Address,' which is needed for residency verification and certain official deliveries. This will result in a request for information (RFI) and delay the application process. Always provide the full street address where you actually live. Tools like Instafill.ai can validate address formats to ensure they meet requirements.
Using an Ambiguous or Incorrect Date Format
When entering dates of birth, applicants may use their local format (e.g., DD/MM/YYYY) instead of the expected U.S. format (MM/DD/YYYY), causing ambiguity and data entry errors. This can create significant problems with identity verification and eligibility checks. To avoid this, use the specified format or write out the month (e.g., 05-APR-2001) to prevent confusion. AI form fillers like Instafill.ai can automatically format dates correctly.
Mishandling the Middle Name Field
When an applicant has no middle name, they might incorrectly enter 'N/A' or 'None' instead of leaving the field blank as instructed. This can be misinterpreted by systems as an actual name, causing a data mismatch with official documents. If you do not have a middle name on your passport, you must leave the field completely empty. If the form is a non-fillable PDF, tools like Instafill.ai can convert it to a fillable version, making it easier to manage fields correctly.
Failing to Disclose or Update Pregnancy Status
An applicant who is pregnant may forget to fill out the pregnancy section or fail to update their form if they become pregnant after the initial submission. This is critical information as it affects medical examinations, travel planning, and the need to register the newborn. Failing to disclose this can lead to major logistical complications and delays near the time of travel.
Incomplete U.S. Contact Information
When listing family or friends in the U.S., applicants sometimes provide incomplete addresses (e.g., missing a ZIP code or apartment number) or outdated phone numbers. This information may be used for verification, and incorrect details can hinder the process or cause important documents to be lost. Before submitting, confirm the full, current address and contact details with your U.S.-based contacts. Using a tool like Instafill.ai can help by storing and accurately populating this information from a saved profile.
Vague Occupation or Skill Description
In the 'Occupation or Skill' field, applicants may use overly broad terms like 'Manager,' 'Consultant,' or 'Engineer' without providing necessary context. This lack of detail can make it difficult for consular officers to assess the applicant's background and qualifications, potentially triggering requests for additional evidence. Be specific by providing a clear job title and a brief description of your industry to avoid delays.

I am the main applicant. Do I check 'Yes' or 'No' for 'Principal Applicant'?
