The Statement of Purpose paragraph that does the work.

A Statement of Purpose is, in immigration practice, an answer to one question: Why are you going there, and why are you coming back? Anything that does not directly support those two clauses is decorative.

The paragraph that does the work is paragraph two. Paragraph one is your introduction (one or two sentences only). Paragraph three is your closing statement of intent. Paragraph two — the load-bearing one — is where you spell out: dates, places, who you're seeing or meeting or photographing, and what brings you back.

A useful template: "From [date] to [date] I will be in [city] to [verb]. I will stay at [hotel/host]. After [date], I will return to [home country] to resume [job/study/family responsibility]." That's it.

The temptation is to embellish — talk about your love of culture, your hopes for the trip, your appreciation of the destination. Resist it. Embassies see thousands of these. The applicant who states the facts cleanly looks more credible than the one who waxes lyrical.
