Yes, UK citizens can apply for an Indian visa at Indian diplomatic missions in both Bangkok, Thailand and Singapore, provided they meet the eligibility criteria and submit the required documentation.
The Indian Embassy in Bangkok accepts visa applications from UK passport holders. Applicants must complete the online application form, schedule an appointment, and submit their passport, photos, supporting documents (such as proof of residence in Thailand or travel itinerary), and the applicable fee. Processing times and specific requirements can change, so it is essential to check the embassy's official website or contact them directly before applying.
Similarly, the Indian High Commission in Singapore processes visa applications for UK citizens. The procedure is comparable: online registration, appointment booking, and submission of physical documents including a valid passport, completed application form, photographs, and visa fee. Since requirements vary by visa type (tourist, business, medical, etc.), verify the latest guidelines on the High Commission's website.
