Hello, I have experienced something similar recently with another tech company, where the hiring manager, HR and myself had agreed on everything including me applying for a visa au my own cost (and naturally stopping the interview process with several other companies). They weren't strangely silent for a month. I applied for the visa, got it andOl once I announced that I had the visa, they didn't want to employ me anymore, citing that the role had been "reformed".

I learnt a month later that my colleague was leaving for this company and position.
