How does the novel use irony to critique migration?

Irony occurs when there is a gap between expectation and reality. In The Lekki Headmaster, the novel uses situational irony to critique migration by showing how the anticipation and excitement surrounding the decision to move abroad contrasts sharply with the actual hardships migrants face upon arrival.

Characters in the novel look forward to leaving Nigeria with great optimism, imagining that life overseas will be better in every way. However, the reality they encounter - or that is reported back to them - involves difficult working conditions, social isolation, discrimination, and the loss of professional status. This gap between the hopeful departure and the harsh reality is the irony the novel highlights.

The novel does not argue that migration is always a failure, nor does it suggest that people universally regret leaving Nigeria. It also does not claim that Nigerian schools are superior to foreign institutions. Instead, it takes a more nuanced position by using irony to reveal that the dream of migration often does not match the lived experience, prompting readers to question the assumptions behind the desire to leave.
