Module to help Indian companies generate sponsorship letters for inviting foreign professionals in National Single Window System

Department for Promotion of Industry and Internal Trade (DPIIT), Ministry of Commerce and Industry has launched an online module for Indian companies to generate sponsorship letters for inviting foreign professionals for production related activities under the e-Production Investment Business Visa (e-B-4 Visa) on 29th November, 2025. The launch of this digital platform is a part of a series of reforms that the Government of India has instituted under the business visa regime for improving the ease of doing business in India.

In August 2025, the Ministry of Home Affairs issued a Circular for resolving certain issues related to employment visa, business visa and e-PLI business. As part of this circular, two activities which were earlier covered under the employment visa namely, Foreign nationals coming for installation and commissioning of equipment (i) as part of contract of supply of equipment and (ii) for which Indian companies pay fees or royalty, are now brought under the business visa regime. Further, a new sub-category of "Production Investment Visa" has been created under the Business Visa regime and called the "B-4 Visa" for enabling foreign subject matter specialists/ engineers/ technical people being engaged by Indian companies under the following categories: a) installation and commissioning; (b) quality check and essential maintenance; (c) production; (d) IT and ERP Ramp-up; (e) training; (f) supply chain development for empaneling vendors, (g) plant design and bring-up; and (h) senior management and executives to visit India for such production investment activities seamlessly. Moreover, the existing e-PLI business visa was dispensed with. The Ministry of Home Affairs also made amendments to relevant chapters of the Visa Manual, 2019.

As part of this reform, this Production Investment Visa will be issued as an e-visa and has to be applied for in the online Visa portal. Further, to facilitate the Visa application process for e-B-4 visa, Indian companies shall generate sponsorship letter digitally. For enabling this facilitation digitally, DPIIT had launched the e-Production Investment Business registration module on the National Single Window System (NSWS) on 29th November, 2025, which can be availed by PLI as well as non-PLI businesses.

Processes have been streamlined with simpler forms and recommendation requirement of the Line Ministry has been done away with.  With this module, Indian companies and Limited Liability Partnerships (LLPs) can instantly generate sponsorship letters for inviting foreign professionals for production related activities under the e-B-4 Visa category on NSWS (https://www.nsws.gov.in). The Auto population of data and automatic authentication through existing data bases like MCA, GSTN etc. have eliminated the requirement of approval of line ministry. The unique ID of the generated Sponsorship Letter shall be referred by foreign professional when he applies for Visa on the e-Visa portal (https://indianvisaonline.gov.in) where the module has been integrated with NSWS through API.

Digital NSWS module lets Indian firms generate sponsorship letters for e-B-4 production investment visas, streamlining e-visa applications. DPIIT launched a National Single Window System module allowing Indian companies and LLPs to generate sponsorship letters for the e-Production Investment Visa (e-B-4); the module auto-populates and authenticates data from existing databases, issues a unique sponsorship-letter ID for the e-visa application, removes the line ministry recommendation requirement, and integrates via API with the e-visa portal to streamline the application process.
