I don't intend on taking vaccinations and will be filing I-601
Does this mean I dont have to worry about I-693?
Thanks!
It's not up to you whether you get the vaccinations or not - if you don't have proof that you had them before, you will have to have them now.
You can opt out of them if it is against your religion. Nevertheless, you have to provide sufficient proof (and filing form 601 is not free either)
