Cultural Tip
In French, using the abbreviation 'infos' is common in everyday conversation and informal emails, but avoid it in formal reports or official documents. Also, the inverted conditional (devrais‑je) adds a polite nuance; a more casual alternative would be 'Je devrais rassembler quelles infos ?' which is less formal and more conversational.
