What is the correct way to add a foreign key?

Question

Laravel

I couldn't come up with a name for the table, I decided to add these two fields to the user table :)

subscription_id
subscription_ends_at

I want to add FK to subscription_id , but the problem is that the subscriptions table has not yet been created during migration.

Of course, you can make sure that the subscriptions table is created before the user table, but it seems to me that this is already a crutch.
What can be done?
