(ASSAM, INDIA) Prime Minister Narendra Modi has renewed his pledge to address illegal migration from Bangladesh, a long-running flashpoint across India’s northeast and eastern states. The push comes as Assam expands its network of detention centers and steps up deportations, with local leaders arguing that unchecked cross-border movement strains jobs, land, and security.
While New Delhi presses Dhaka to accept returnees, Bangladesh questions the scale of the problem, slowing the pace of removals and keeping tensions high along the border.

Recent enforcement actions
Indian officials have recently moved visible enforcement measures to the front. Between December 31, 2024, and January 2, 2025, 30 individuals were deported, according to reports shared with state authorities. These cases reflect a broader drive to identify and remove people found to be in India without valid documents.
The government maintains detention centers in Assam and Delhi to hold detainees ahead of deportation, saying the facilities are needed to manage cases while travel documents are verified and travel is arranged.
Assam’s role and detention infrastructure
Assam has taken a lead role in the enforcement drive. The state’s existing facilities operate in:
- Goalpara
- Kokrajhar
- Silchar
- Dibrugarh
- Jorhat
- Tezpur
Officials say new sites are under construction to add capacity as enforcement grows. Authorities argue these centers are essential to:
- Maintain custody and limit absconding
- Coordinate with foreign missions for travel permits
- Provide separate infrastructure for families that respects child welfare rules (housing arrangements vary by site)
Assam Chief Minister Himanta Biswa Sarma launched a high-profile drive in August 2025 to identify and deport illegal Bangladeshi migrants and to reclaim public land he says was encroached upon during earlier settlement waves. State police, border units, and district administrations were directed to run coordinated checks. The state government contends that focused enforcement restores confidence among local communities who believe past efforts were uneven or too slow.
Security and border context
Security officials warn that illegal migration can create blind spots that extremist groups may try to exploit. Investigators have linked the Ansarullah Bangla Team (ABT) to activities aimed at sensitive corridors, including the Siliguri Corridor that connects the northeast to the rest of India.
While such cases are not the norm, they bolster support for tighter vetting and faster removals. The Union government has pushed for stricter border management and closer coordination between states and central agencies to track irregular entries and forged documents.

Historical and social roots
The roots of today’s tensions run deep. Many families crossed into India during and after the 1971 Bangladesh Liberation War. The 1985 Assam Accord promised a framework to identify and address post-1971 entrants, but progress has been uneven and documentation gaps remain.
Over time, local leaders in Assam, West Bengal, and Bihar say demographic shifts changed village economies and electoral landscapes. These claims are hotly debated, yet they continue to shape district-level politics.
Economics compounds the issue:
- Employers may hire undocumented workers at lower wages, undercutting local labor markets.
- Residents argue this wage pressure depresses incomes for lawful workers and fuels resentment.
- Community groups express cultural concerns about rapid arrivals altering schools, markets, and places of worship.
Officials warn these social tensions can flare during elections or land disputes.
Politics, policy, and human impact
Prime Minister Modi has vowed a cleanup of illegal migration but has not outlined new timelines or specific legislative steps recently. The central government’s approach remains:
- Reduce irregular crossings
- Tighten legal pathways
- Pursue diplomatic solutions with Bangladesh
Indian officials say cooperation is needed to verify identities and issue travel permits. However, Bangladesh has not acknowledged the magnitude of illegal migration claimed by Indian states, complicating removals and slowing returns.
Experts diverge on future developments:
- Some economists highlight Bangladesh’s rising per capita income and improved job prospects, suggesting the pull into India may be weaker than before.
- Political analysts note the issue retains electoral weight, with parties sometimes framing migration to rally supporters.
On the ground, enforcement measures—house-to-house verifications, workplace raids, and checks—remain deeply personal for families whose status is questioned.
Operational pathway and practical effects
Assam’s operational map shows the infrastructure built to support enforcement. The typical pathway for identified cases runs:
- Identification
- Detention
- Consular coordination
- Removal flights or escorted border transfers
Without valid travel papers from Bangladesh, cases can remain in limbo for months.
For those flagged as suspected illegal migrants, the stakes are immediate:
- Detention separates families and halts income
- Increased fear in neighborhoods where many speak Bengali at home
- Mixed-status families may face intrusive checks
- Workers worry about wage competition and land pressure
- Small business owners fear penalties if inspectors find undocumented staff
District officials say complaint lines are open, but they caution against false reporting that can inflame tensions.
The core challenge: differentiating long-settled residents, citizens, and recent entrants remains legally and administratively sensitive.
Policy trade-offs and forward-looking measures
Policymakers must navigate trade-offs. Measures widely supported across parties include:
- Border fencing
- Better identity checks
- Faster case processing
But implementation is resource-heavy and legally complex. Verifying nationality requires record-sharing and bilateral cooperation that only moves as fast as both countries allow.
Looking ahead, New Delhi and Dispur are expected to continue:
- Stepped-up enforcement
- Construction of new detention centers
- Regular deportation drives
The central government emphasizes pairing law enforcement with talks with Bangladesh to ensure returns are humane and lawful. According to analysis by VisaVerge.com, states will likely press for faster identity verification pipelines so detainees are not held longer than necessary and removal orders can be carried out promptly.
Practical steps for stakeholders
- For migrants:
- Expect ID checks, workplace inspections, and targeted drives
- Those without valid documents face detention and deportation
- For local communities:
- District administrations may add curbs on unlawful land use
- Job-site audits may expand to deter illegal hiring
- For policymakers:
- Continued focus on bilateral coordination, case tracking, and legal reforms to clarify status determination and appeal rights
Unresolved core dispute
The central disagreement remains: how many people from Bangladesh are in India without status, and how quickly can both sides process returns? Until those answers align, India’s border states will continue treating illegal migration as a top law-and-order concern, while families on both sides of the border live with persistent uncertainty.
This Article in a Nutshell
India, led publicly by Prime Minister Narendra Modi, has intensified enforcement against alleged illegal migration from Bangladesh, with Assam taking a lead role. Authorities expanded detention infrastructure across several districts — Goalpara, Kokrajhar, Silchar, Dibrugarh, Jorhat and Tezpur — and reported deportations, including 30 individuals between December 31, 2024 and January 2, 2025. The drive includes house-to-house checks, workplace raids and coordinated searches, supported by plans for additional detention capacity. Bangladesh has questioned India’s assessment of the scale of irregular migration, slowing repatriations and complicating verification. Officials argue stricter border management and faster identity pipelines are needed to reduce detention times, while analysts warn of socioeconomic tensions, legal challenges and the need to protect human rights during the process.
