Are Bangladeshi Illegal Immigrants in India a Real Issue, or Just Politics?

You may have recently come across news about Saif Ali Khan's alleged attack, where Bangladeshi illegal immigrants are supposedly involved.

I don’t understand why Bangladeshis would settle illegally in India when the job market there isn’t much better than in Bangladesh. From what I see, people might cross the border illegally for reasons like drugs, curiosity, or alcohol—things harder to access in Bangladesh—but India doesn’t seem to offer anything substantial that would attract Bangladeshis to settle illegally.

On the other hand, there’s a noticeable presence of illegal Indians living and working in Bangladesh, both in skilled and unskilled sectors especially in Garments.

So, is this narrative about illegal Bangladeshi immigrants a genuine concern, or is it just part of BJP’s Muslim hatred politics?

With India having one of the best intelligence agencies and BJP controlling the central government, including agencies like BSF, wouldn’t they have accurate data on migration trends?

What do you guys think? Are illegal immigrants really a widespread issue, or is this just politics at play?
