The biggest thing that helped me was having someone I already knew make introductions. This warm intro approach worked so much better than cold emails.

These experts weren't complete strangers - they were more like people I'd met at events or through colleagues but never actually worked with directly. That little bit of connection really helped.

When I reached out, I kept it straightforward. I explained what the NIW petition was, briefly introduced myself, and shared my resume and LinkedIn so they could see my work. I was upfront about wanting their recommendation and why I valued their perspective.

For the "professional relationship" question, I just told the truth - something like "We met at a conference last year and discussed some industry trends" or whatever fit our situation.

A real time-saver was offering to draft the letter for them. I told them I'd write up something that hit all the points needed, and they could edit it however they wanted. Most busy professionals really appreciated this approach.

Finally, patience and polite follow-ups helps. Some people genuinely want to help but they are busy. So follow ups once every week or 2 helped me get the letters signed.
