I recently got my F-1 --> O-1 change of status approved. I need to travel to my home country to get a visa stamp and for other urgent personal reasons. Due to consular appointment unavailability, it seems like I will stay in my home country for a period of 5 weeks. I was wondering if this will invite scrutiny at POE, especially pre-clearance airports like Abu Dhabi/Toronto? Technically, there is no LCA for O-1, and it is not 'tied' to a particular location in the same way that H-1B is. If I have the I-797A and visa stamp, along with written approval for short-term, international remote work from my employer, would that be enough? I'd appreciate any input, thanks! I've also contacted my attorney with this question. I was wondering if anyone has gone through similar experiences in the past. Thanks!
Update: My attorney mentioned that a letter from the employer and the attorney that authorizes remote work should be enough. I was also advised to avoid pre-clearance airports.
