In principle it does not matter whether the sentence is conditional or unconditional. It also does not matter if you received the sentence in the Netherlands or abroad. Nor does it matter if you have been pardoned for (part of) the sentence. The IND or local council always looks at the sentence you received before the pardon.

Have you been granted Dutch nationality? And later it appears that you withheld information (for example about your criminal history)? Your nationality may be revoked if you should not have been given Dutch nationality as a result of this information.
