This question is in relation to 2 types of foreigners:
1) Regular foreigners (eg. from Western Europe, etc.)
2) Marginalized foreigners (eg. Muslims, Russians, etc.)
To further expand on what I mean by "outlook": Are foreigners welcome in the US in this political climate? Can foreigners expect extra/excessive bureaucracy (especially type 2) foreigners) from authorities? Does YC play a role in assisting type 2) foreigners who may experience 'issues'?
