While it's generally not recommended, IMO this one of scenario where brainwallet or having encrypted cloud backup may help you.

One of recommendations is having multiple backups at different locations but I know it's non sense in deportation case too. It's because most of Bitcoin users are very unlikely have ability to store wallet backups in different nations. Even if we can, I am not sure it is a safe wallet backup storage in practice.

Usually it's not common to take wallet backup storage too far like this by lack of chance for regular backup checks which is a very important step in wallet backup storage.

Geographic Diversity

If any single location has enough key material that a physical attacker could use it to steal funds, you have a single point of failure. You'll want to spread your backups across a variety of physically secure / hard to find locations so that it's unlikely that any single disaster or attacker will be able to cause a simultaneous loss from multiple locations.

However, you don't want to take this too far! While you want it to be unlikely for an attacker or some event to be able to compromise your seeds, you also need to be able to check them every once in a while to ensure that they have not been compromised. If you never check your backups then a patient attacker could spend years slowly compromising enough of them that they can reconstitute your keys and steal your funds without you realizing until it's too late.

It is not recommended to use brains but if my practice is diversifying my coins to different wallets, at least I will try to use my brain and memory to remember wallet mnemonic seed of a biggest wallet.
