It seems that EU/Asian/Middle Eastern citizens have the opportunity to apply for several self-funded programs which (upon acceptance and completion) guarantee a job as a first officer on small twin engine aircraft flown by the sponsoring airline. Is there any such program available to US citizens? And if so, what makes an applicant competitive?
Many of the Asian ones are only open to their own nationals, to give them the opportunity to become a pilot as well. Pilots are in demand, and particularly captains are hard to find. For the funding, many F/Os are now self funded, low cost airlines do usually not fund initial pilot education.
An outfit like Stella Aviation in The Netherlands did offer bank loans to fund the license, guaranteed until the student found a job.
Unfortunately, we don't see many USA citizens working as expats: they are often very expensive due to having to pay double taxes when working abroad, USA has historically had few tax agreements with other countries.
