Do I need to fill out form 8843 if I'm not exempt but also do not meet the substantial presence test?
It would not be a problem to file 1040-NR without the 8843. After all, the purpose of the 8843 is to exclude days of presence in the USA for the purposes of the Substantial Presence Test. If none of the days during the tax year qualifies for exclusion do not attach the form.
