In a landmark move to simplify travel and enhance bilateral relations, Kuwaiti citizens can now apply for Indian e-visas entirely online beginning Monday, July 14, 2025. The announcement was made by Dr. Adarsh Swaika, India’s Ambassador to Kuwait, who described the launch as a “qualitative shift” in India-Kuwait engagement.

The new digital platform covers five visa categories: tourism, business, medical, conference, and AYUSH (alternative medicine including yoga and Ayurveda). Applicants no longer need to visit visa centers; all steps including application submission, document upload, and payment are completed online.

Key features of the e-visa system include:

Tourist visas valid for up to five years at a fee of $80
Other visa fees range from $40 to $80 depending on type and duration
Biometric data collection upon arrival at Indian airports
Typical processing time of three to four days, with minor technical issues possible during rollout

Ambassador Swaika emphasized that this initiative responds to a long-standing request from Kuwaiti citizens and reflects the deep historic and cultural ties between the two nations. The move also aligns with India’s broader efforts to modernize consular services and strengthen diplomatic and people-to-people connections in the Gulf region.

The e-visa allows for a variety of short-term activities such as tourism, business meetings, medical treatment (including under Indian traditional medicine systems), attending conferences, and participation in yoga or Ayurveda programs.

Applicants must hold a passport valid for at least six months and possess a return or onward ticket. The Indian Consulate in Kuwait will continue to accept paper visa applications for those who prefer traditional processing.

This digital visa rollout is expected to boost travel, trade, and cultural exchange between India and Kuwait, supporting the growing interest among Kuwaitis in Indian tourism, healthcare, and business opportunities.
For more information and to apply, Kuwaiti citizens can access the official Indian e-visa portal, which provides guidance in both English and Arabic.

This development marks a significant step forward in facilitating seamless cross-border travel and enhancing the longstanding friendship between India and Kuwait.

The United Arab Emirates has officially denied rumours of a lifetime Golden Visa offer for Indians and certain other nationalities, following widespread reports and social media buzz suggesting otherwise. The Federal Authority for Identity, Citizenship, Customs and Port Security (ICP) of Abu Dhabi clarified that no lifetime Golden Visa scheme exists, and all applications are processed strictly through official government channels within the UAE.

The ICP emphasized that the eligibility categories, conditions, and regulations for the Golden Visa are clearly defined by UAE laws and ministerial decisions, and no internal or external consultancy or commercial entity is authorized to handle or facilitate visa applications. This statement was issued in response to misleading reports claiming that Indians and Bangladeshis could obtain a lifetime Golden Visa for a fee of approximately ₹23 lakh (AED 100,000) through private consultancies, notably the Dubai-based Rayad Group, which later apologized for the confusion caused.

The authority warned the public against falling prey to fraudulent schemes promising simplified or guaranteed visa approvals, noting that such claims have no legal basis and were made without coordination with UAE authorities. The ICP also announced that legal action will be taken against entities spreading false information and illegally collecting money from hopeful applicants.

Applicants seeking accurate and up-to-date information on the UAE Golden Visa program are urged to rely solely on official sources, such as the ICP’s website and smart application platforms. The Golden Visa process remains transparent and regulated, with no shortcuts or lifetime residency offers outside the established legal framework.

This clarification comes amid growing enthusiasm among Indian nationals for UAE residency options, but the ICP’s firm denial aims to curb misinformation and protect applicants from exploitation.

Authorities in Oman have unveiled detailed plans to transform the old Muscat airport terminal, which spans a 50,000 square meter site, into a major leisure and commercial destination. The redevelopment will follow a Build-Operate-Transfer (BOT) model, with interested developers invited to submit Expressions of Interest by July 9, 2024.

Overseeing the project is Oman Airports Management Company, part of the Oman Investment Authority, which aims to create an upscale, mixed-use hub that integrates retail outlets, restaurants, business centers, and multi-level parking, alongside a proposed aviation museum to celebrate Oman's aviation history.

The site’s prime location at the intersection of Sultan Qaboos Highway and Muscat Expressway ensures excellent connectivity to major city landmarks, including the Oman Convention & Exhibition Center, luxury hotels, and shopping malls. The Greater Muscat Master Plan also anticipates a future metro station adjacent to the site, which is expected to drive significant visitor traffic and commercial interest.

The old terminal, which opened in 1973 and served as Oman’s main airport until 2018, will be revitalized to honor its historical significance while providing modern amenities. The aviation-themed redevelopment will include an aviation museum, shopping centers, restaurants, and entertainment venues, aiming to attract both local residents and tourists.

The project is designed to enhance Muscat’s urban landscape and contribute to the city’s economic development by drawing high-end tenants, investors, and real estate developers.

The transformation is also aligned with Oman’s National Aviation Strategy 2030, which seeks to attract $3.6 billion in airport city investments and open the sector to private and international investors. The redevelopment emphasizes sustainability by repurposing the existing terminal structure, reducing environmental impact compared to new construction.

The selection process for the developer will continue through the summer, with site visits already scheduled for interested bidders. Once completed, the new leisure hub is expected to become a landmark destination, reflecting both Oman's aviation legacy and its ambitions for future growth
