Big fuck up on her boss here. You don't send your immigrant workers on a visa (especially from countries currently involved in a war) to be mules for you, since their visas can always be cancelled for any reason, so why are you putting them in situations where they can give authorities a reason?
How do they not know this? What were they thinking? Either go yourself or send someone else who's a citizen. The lack of thought in this just boggles my mind.
Also, where's the self preservation on her part, especially given her via situation and the situation in her country? When I as an immigrant traveled for work with hardware prototypes , I always made sure my boss had them in his luggage since he's a citizen with a more powerful passport and I don't want to be flagged by border controls on what's a foreigner doing with strange hardware in his luggage.
You don't just accept to be a mule for your employer when you're an immigrant on a visa since then you're just playing Russian roulette(pun not intended). If I were a Russian citizen on a visa abroad right now, I'd do everything in my power to lay low, fly under the radar and avoid all unnecessary travel, or travel with only pajamas and a toothbrush, not with animal embryos. I guess biology scientists are so used to travelling with weird shit all the time, they just forget to declare it.
Edit: @downvoters, do you have any arguments to add?
