Maybe there is more paperwork if they let you go on the first day (but for the HR people it is just doing their job - to do that paperwork!), but I don't think so. It is also very common to have a short (1 week max) notice for the probation period, so they will let you go if there are any issues. The reason why you had a job was most probably not the amount of paperwork they would have had to do had they really wanted to fire you. Maybe you were doing your job right?
And what if you are without a job for some time? Unless you are just starting out from nothing, your you depend on a visa, it is not the end of the world... Some people even do it on purpose.
Yeah, when I took my current job I was more in the vein of "How much time off can I take that you won't mind?" We settled on something like 3 or 4 weeks and I booked a vacation.
Sure, stuff can happen. But I try not to be paranoid about what are low probability events at the end of the day that I only have limited control over.
