- 11Why KAHEM
The introduction of India's e-B-4 Production Investment Business Visa has created a streamlined route for eligible Chinese nationals travelling to India for production, manufacturing, technical and investment-related activities.
At KAHEM, we specialise in assisting Indian businesses with the documentation, sponsorship/invitation process and visa application support for Chinese nationals — including cases where the Indian sponsoring entity is not supported by the standard NSWS digital sponsorship mechanism.
What Is the India e-B-4 Visa?
The e-B-4 Production Investment Business Visa is a specialised Business Visa category for eligible foreign nationals undertaking specified production and investment-related activities in India.
For Chinese nationals, the category is particularly relevant to businesses requiring technical expertise from China for activities such as:
- Machinery installation and commissioning
- Production and technical support
- Quality checks
- Essential maintenance
- IT and ERP ramp-up
- Technical training
- Supply-chain development
- Vendor empanelment
- Plant design and bring-up
- Production ramp-up
- Visits by senior management and executives
Listed as an e-Visa category
The Embassy of India in Beijing lists the e-B-4 Production Investment Business Visa as an e-Visa category.
Why Choose KAHEM?
Expertise in Chinese National Visa Processing
Visa applications involving Chinese nationals can require careful preparation, particularly when the applicant is travelling to India for a technical, manufacturing or production-related assignment. KAHEM provides specialised assistance in structuring and coordinating these cases.
Our strength lies in understanding both sides — bringing the Indian business, the Chinese professional, the production activity and the visa documentation together into a clear and consistent application.

End-to-End Documentation Support
From initial assessment to document preparation and application support, KAHEM helps coordinate the complete process.
The Non-NSWS Challenge
What if your Indian business is a partnership firm?
This is one of the areas where businesses frequently face difficulties. The Government's digital NSWS Production Investment Business Registration facility is designed for Indian companies and LLPs to generate the digital sponsorship letter for eligible production-investment visa cases.
But many genuine Indian businesses operate through other structures, including:
- Partnership firms
- Traditional business entities
- Other eligible organisations / entities
A partnership firm should not attempt to use an unsupported NSWS entity type or create an incorrect sponsorship record. This is where KAHEM can help.
KAHEM assists in evaluating and preparing non-NSWS cases, ensuring that the Indian firm's legal status, business activity, commercial relationship and requirement for the Chinese professional are properly documented.
Important
A non-NSWS case is not an automatic alternative route to visa approval. The proposed activities must independently satisfy the applicable Indian visa requirements.
How KAHEM Handles a Non-NSWS Case
- 1
Initial Case Assessment
We understand the nature and legal constitution of the Indian business, the proposed Chinese applicant and employer, the purpose of travel, the production/investment project, the proposed activities in India and the expected duration — then assess whether they appear appropriate for the e-B-4 category.
- 2
Entity & Business Verification
For partnership firms and other non-NSWS entities, we review available business documentation — partnership deed, firm registration, PAN, GST, Udyam, IEC, financials, business profile and factory/plant documents — to establish the legitimacy and nature of the Indian business.
- 3
Applicant Assessment
We review the Chinese professional's passport, employment details, designation, qualifications, technical experience, employer and proposed assignment. The applicant's background should be consistent with the proposed technical or production activity.
- 4
Commercial & Technical Documentation
Where applicable, we review purchase orders, machinery invoices, equipment and technical/technology agreements, project and import documents, training requirements and plant commissioning documents to establish the genuine business purpose of the visit.
- 5
Sponsorship / Invitation Documentation
We prepare a structured sponsorship/invitation package explaining who is inviting the applicant, why they are required, what they will do, where activities take place, how long they continue, and the relationship between the Indian and Chinese parties.
- 6
Visa Application Support
Once documentation is ready, KAHEM assists with the applicable online visa application and supporting documents. The e-B-4 category is processed through India's e-Visa system for eligible applicants.
- 7

Why Professional Documentation Matters
A successful visa application is not simply about completing an online form. For a production-investment case, the authorities need to be able to understand the commercial purpose of the visit.
A well-prepared case should create a logical connection:
KAHEM focuses on creating this documentary consistency before the application is submitted.
e-B-4 Visa vs Employment Visa
It is important not to confuse the e-B-4 Production Investment Business Visa with an Employment Visa. The correct visa category depends on the actual activities proposed in India.
| e-B-4 Production Investment Business Visa | Employment Visa |
|---|---|
| Production-investment business activities | Employment in India |
| Technical / production assignments | Regular employment |
| Machinery installation & commissioning | Employment duties |
| Qualifying training | Employment-related responsibilities |
| Plant design / bring-up | Long-term employment |
| Supply-chain development | Salary-based employment |
| IT / ERP ramp-up | Depends on employment role |
If the applicant will undertake regular employment, the Employment Visa framework should be separately considered.
Common Problems We Help Businesses Avoid
Incorrect visa category
Applying under a Business Visa when the proposed activity actually amounts to regular employment.
Unsupported NSWS entity
Trying to use an NSWS sponsorship mechanism for an entity type that is not supported.
Weak invitation letter
Using a generic invitation that does not explain the technical requirement.
Inconsistent documents
Indian and Chinese documents describing different purposes for the visit.
Insufficient commercial evidence
Failing to establish the relationship between the Indian business, project and Chinese professional.
Incorrect applicant role
The applicant's professional background does not adequately match the proposed assignment.
Treating sponsorship as a guarantee
A sponsorship or invitation document does not guarantee visa approval — the final decision rests with the competent Indian authorities.
Frequently Asked Questions

Yes. The Embassy of India in Beijing lists the e-B-4 Production Investment Business Visa as an e-Visa category for eligible applicants.
Installation and commissioning are among the activities covered by the production-investment framework, subject to applicable requirements.
Qualifying production-investment training activities are covered by the framework.

Partnership firms are not expressly identified as a supported entity type in those materials.
The case should be assessed individually and presented through the applicable official immigration/visa process with appropriate evidence of the firm's legal existence, business activity, production/investment requirement and the Chinese professional's proposed activities. KAHEM specialises in assisting with such non-NSWS cases.

Your Indian Business, Our Visa Expertise

- Visa category evaluation
- Non-NSWS case handling
- Sponsorship & invitation documentation
- Chinese applicant documentation

Important Disclaimer
This content is intended for general informational purposes only and does not constitute legal advice or a guarantee of visa approval. Visa rules, eligibility requirements, documentation requirements and procedures may change from time to time. The applicability of the e-B-4 category depends on the applicant's circumstances and the actual activities proposed in India.
The current official NSWS information identifies the Production Investment Business Registration facility for Indian companies, while DPIIT has stated that Indian companies and LLPs can generate the digital sponsorship letter. The official materials reviewed do not establish an equivalent automatic NSWS sponsorship-letter mechanism for partnership firms. Non-NSWS cases therefore require individual assessment and appropriate handling through the applicable Government of India process.
A sponsorship or invitation letter does not guarantee the issuance of a visa. The final decision rests with the competent Government of India authorities. Applicants should verify the latest requirements through the official Government of India immigration and visa channels before submitting an application.
