Frequently asked questions — Dependent Visa (Non-O) in Sai Mai
Can a Dependent Visa (Non-O) be applied for from Sai Mai, or do I need to travel to Bangkok?
From Sai Mai you can complete most steps remotely. NYC Legal collects your documents via courier or our Line/WhatsApp document portal, prepares Thai-translated drafts for your review, and only requires you to travel to the relevant Immigration office on the submission day itself. For applicants in Sai Mai, we also offer a hybrid service where our paralegal collects originals at your residence and returns the visa-stamped passport by EMS.
How long does the Dependent Visa (Non-O) process take when filed from Sai Mai?
Standard processing for Dependent Visa (Non-O) is 1-2 weeks. From Sai Mai you should add 1–3 working days for document courier and translation. Express handling is available — NYC Legal pre-checks every form before submission, which avoids the typical 7–14 day rejection-and-refile cycle that solo applicants experience at provincial Immigration offices.
What is the total cost of a Dependent Visa (Non-O) for someone living in Sai Mai?
Government fees are THB 2,000. NYC Legal's professional service fee is THB 10,000-15,000, which covers eligibility screening, document preparation, MoJ-certified translation, MFA legalization, embassy authentication where required, in-person Immigration submission, and 12 months of post-issuance compliance support (90-Day Report reminders, TM.30 advice, Re-Entry Permit). No hidden fees.
Which Immigration office serves Sai Mai?
Each district and province in Thailand is assigned to a specific Immigration Bureau division. NYC Legal verifies the correct office for Sai Mai on every file because the wrong office means automatic rejection. We escort you in person on submission day, having pre-confirmed the queue number, officer assignment, and document checklist.
What happens if my Dependent Visa (Non-O) application is rejected?
Rejections at the Immigration Bureau usually stem from missing translations, expired financial documents, or wrong office filing. NYC Legal's pre-submission review eliminates these. In the rare case of rejection on a NYC Legal file, we re-submit free of charge — only government fees are paid again. We have a full pre-submission review for Dependent Visa (Non-O) files.
Do I need certified translations for the Dependent Visa (Non-O) application from Sai Mai?
Yes. Every foreign-language document submitted with a Thai visa application must be translated into Thai by a translator registered with the Thai Ministry of Justice. NYC Legal's in-house MoJ-registered translators prepare the translation, then we legalize it at the Department of Consular Affairs (MFA Chaeng Watthana) within 2 working days. This package is included in the service fee for clients in Sai Mai.
Can NYC Legal handle Dependent Visa (Non-O) for clients across multiple provinces simultaneously?
Yes. We handle Dependent Visa (Non-O) files from all 77 Thai provinces, all 50 Bangkok districts, every BTS/MRT station area, and major shopping malls. Sai Mai clients get the same fixed service fee, same lawyer-led process, and same 12-month post-issuance support as Bangkok clients.
