- ✓ Update OCI online whenever your passport is renewed—failure can result in denied boarding
- ✓ Apostille (not notarization) is required for all documents issued outside India
- ✓ Get apostille documents BEFORE you leave your home country
1️⃣ Renunciation – The Mandatory First Step
As soon as you acquire foreign citizenship, your Indian citizenship automatically ceases to exist by law. India does not allow dual citizenship under any circumstances. According to the Ministry of External Affairs, renunciation is mandatory before applying for OCI status.
The Legal Timeline
You have 3 months from acquiring foreign citizenship to formally renounce your Indian passport.
Renunciation Process
- Go to the nearest Indian Embassy or Consulate
- Fill out renunciation form
- Submit your Indian passport
- Pay the renunciation fee (typically ~$200–$300)
- Processing time: 2 weeks
Why This Matters (Even If You Don't Want OCI Later)
- Legal requirement: After 3 months, you're technically holding a passport of a country whose citizenship you've already lost
- Travel complications: If you travel on an Indian passport after gaining foreign citizenship, you could face legal issues at borders
- Employment verification: Future employers may ask about citizenship status
- OCI timing: You cannot apply for OCI until you've officially renounced
"I definitely recommend doing the renunciation process as soon as you become a foreign citizen. It is mandatory, regardless of whether you want an OCI later or not. The process is very simple and not very costly."

2️⃣ Traveling During the Transition – e-Visa vs. Entry Visa
After you've acquired foreign citizenship but before your OCI arrives, how do you travel to India? You have two main options:
| Feature | e-Visa (Tourist/Business) | Entry Visa (X1) |
|---|---|---|
| Cost | ~$160 USD | ~$400–$500 USD |
| Processing Time | 24 hours (sometimes faster) | 4–6 weeks |
| Validity | 6 months (2 visits) | 10 years or until passport expires |
| Application | Entirely online | Embassy/Consulate (paper-based) |
| Best For | Short stays, urgent travel | Long-term relocation |
The 180-Day Clock Explained
If you arrive on an e-Visa, you can stay for up to 180 days (6 months) without leaving India.
What happens on day 181? Two options:
- Option A: Exit & Re-Entry – Travel outside India (Nepal, Sri Lanka, Dubai), stay a few days, re-enter. The 180-day clock resets.
- Option B: In-Country Conversion – Convert your e-Visa to an Entry Visa (X1) while still in India through the FRO portal. Fee: ₹2,000–₹3,000 + penalty (~₹5,000–₹10,000)
"By nature, e-visas are non-convertible and non-extendable. But if you have already traveled and now you have decided to stay for longer than 6 months and you cannot travel outside India, then you can even do it from India itself through an FRRO office."

3️⃣ The OCI Card – Understanding the New "Age 21" Rule
The Overseas Citizen of India (OCI) card is a lifelong visa that allows you to stay, work, and do business in India indefinitely. But it comes with renewal requirements.
What OCI Is
OCI is a status (not a separate passport). It's granted to people of Indian origin who are now foreign citizens and their immediate family members. According to Wikipedia, OCI was introduced in 2005 as a response to demands for dual citizenship from the Indian diaspora.
Duration: Lifelong (no expiry date on the OCI card itself)
Important: Your OCI card is linked to your passport. When your passport expires and you get a new one, your OCI must be updated to reflect your new passport number.
The Critical "Age 21" Rule (Effective 2021)
The Rule: You must renew your OCI only once in your lifetime, at age 21 (or close to it, when you get your first new passport after turning 20).
Why Age 21? Facial features change dramatically from childhood to adulthood. Immigration officers need updated photos and records to verify your identity.
What About Minors' Passport Renewals (Every 5 Years)?
Q: Do they need a new OCI card every 5 years?
A: No. Just update online on the OCI portal. No new card needed.
The process is completely online and free. Upload your new passport photo, signature (or thumb impression for minors), and new passport copy. Within 30–45 days you'll get confirmation.
Key: As soon as you upload your new passport info online, you get an acknowledgement receipt immediately. You can travel with this receipt while the system processes it.
Is This Mandatory?
Yes. Mandatory.
"Everyone should do it because we have seen a lot of cases where people were not able to board the flight because they have not updated their passport on the online portal."
Even though you can sometimes get through without updating, it's risky. It's a 5-minute online update. Do it.
4️⃣ Common Mistakes NRIs Make When Applying for OCI
Date Format Confusion
In India, dates are written DD-MM-YYYY. In the U.S., it's MM-DD-YYYY. After living in the U.S. for years, your brain automatically writes dates in U.S. format.
Solution: When filling OCI applications, triple-check date formats. Write them out: "25 March 1990" to avoid confusion.
Passport Mismatches
Many applicants put their new foreign passport number instead of their old Indian passport number.
Result: Application gets rejected because the system can't find a matching Indian passport record.
Missing Apostille Documentation
This is a major reason for OCI delays. (Covered in detail in the next section.)
Incorrect Spelling
If your OCI application has a spelling variation (e.g., "Mohammed" vs. "Muhammad"), it won't match your passport, and you'll have problems boarding flights.
Solution: Ensure your OCI spelling exactly matches your current passport.
Outdated Passport Information
If your passport has been renewed but you didn't update your OCI, the mismatch causes problems at immigration.
Solution: Update OCI whenever your passport is renewed.
5️⃣ Apostille vs. Notarization – A Critical Distinction
This confusion causes major delays for returning NRIs. The U.S. Department of State handles apostille authentication for federal documents, while state-level documents require apostille from the respective Secretary of State office.
| Feature | Notarization | Apostille |
|---|---|---|
| What It Is | A notary public witnesses your signature | Government body authenticates a document |
| Validity | Valid locally (the state where notarized) | Valid internationally (Hague Convention countries) |
| Cost | ~$25 | ~$25–$75 per document |
| Recognition in India | NOT recognized | Recognized |
"People confuse apostille with notarization. Apostille is not notarization. Apostille is authentication of the document by the issuing authority."
Which Documents Need Apostille?
Any vital document issued outside India that you'll use in India:
- Birth Certificate (CRITICAL): If your child was born in the U.S., Canada, UK, Australia, etc.
- Marriage Certificate: If you were married outside India
- Divorce Decree: If applicable
- Adoption Certificate: If applicable
- Medical/Educational Certificates: Sometimes required
Recent Rule Change (December 2024)
New rule from the Indian Embassy: ALL documents issued outside India (not just foreign countries, but even if you have a U.S.-issued document) now require apostille for OCI applications.
How to Get Apostille
- Identify the issuing authority: Birth certificate → State Vital Records Office; Marriage certificate → County Clerk's office
- Request apostille: Call or visit their office, ask for "apostille of [document name]"
- Payment: Typically $25–$50 per document
- Turnaround: Standard: 5–10 business days; Expedited: 1–2 business days (extra fee)
Important: Get apostille BEFORE you leave the country. If you're already in India and need apostille, you'll have to ask someone back home to get it or use an expensive international service.
"I definitely recommend everyone who is planning to return to India—before they leave from here—apply for the apostille of the birth certificate if they or their kids are born here in the US or Canada, UK, wherever they are moving from."

6️⃣ Post-Arrival Checklist – Four Critical Things to Update
Once you arrive in India as a foreign national, you need to update several systems to ensure you're compliant.
Aadhaar Card – Update Residential Status
Process: Find nearest Aadhaar enrollment center (post office, bank, telecom stores). Take your OCI card + new foreign passport. Tell them you're now a foreign resident.
Why: Your Aadhaar tracks if you're an Indian resident or foreign resident. Affects tax filings, banking, etc.
Income Tax Portal – Update Residential Status
Process: Log in to incometax.gov.in → My Profile → Modify Profile → Update residential status from "NRI" to "NR" or "RNOR"
Why: Tax calculations differ for residents vs. non-residents. Understanding the Indian Tax Bill 2025 and its impact on NRIs is crucial for proper tax planning.
Voter ID & Ration Card – SURRENDER
As a foreign citizen, you're no longer eligible to hold these.
Process: Go to your local voter registration office and ration shop. Surrender your cards. Get written confirmation.
Why: Holding a voter ID as a foreign citizen is illegal. It could complicate future visa or residency issues.
PAN Card – Mark as Foreign National
If you already have a PAN: Update to show you're a foreign national via onlineservices.nsdl.com or Form 49AA
If you don't have a PAN: Apply as a foreign national using Form 49A
Why: Tax filing and financial accounts in India require PAN. Marking yourself correctly prevents complications.
"It has been recently added—this requirement has been recently added for the OCI as well—that you need to surrender your voter card and your ration card."

✍️ Editorial Summary
The legal journey from becoming a foreign citizen to settling as a resident in India is straightforward once you understand the sequence. Renounce your Indian passport immediately (it's mandatory). Choose between e-Visa (fast, 6-month stay) and Entry Visa (slower, long-term). Get apostille documents before you leave your home country (or you'll regret it). Update your OCI when your passport is renewed. And once you arrive in India, spend an afternoon updating Aadhaar, Income Tax status, surrendering old ID cards, and registering your PAN.
These steps take time but prevent the nightmare scenarios: being denied boarding, unable to open a bank account, or being legally non-compliant. The key insight: "Just do it early." Delays compound.
