I stayed for 89 days in the US on an ESTA until May (met my PhD advisor, then took time off to visit friends around the country). I would like to come back for a scientific conference in July to present a paper. The problem is that it will have only been two months between the two, and I am afraid I could get denied. My questions are:
- Is this still an issue if I am only staying for two weeks in July? (the conference + visiting friends in New York). Most previous questions seem to be about coming back for 90 days again. Would it be less risky to shorten my stay?
- What documents can I prepare to make this easier? For example a letter of invitation from the conference, proof that I still rent my flat in my hometown, etc...
For context, I am a French national and still live and work permanently in my home country.
