Yes you would say that you are a resident of VA on December 31, 2017.

However, this does not mean that you are considered a full year resident of the state. For the question, previous state of residence, select "yes" then scroll all the way to the bottom of the list to select "Foreign or US Possession" and enter the date you first arrived in VA. This way, you will only have to file a part-year resident return for VA during the time you were a VA resident.

Please note if you are not a US citizen and are here on a visa -

If this is your first year in the USA, your US filing status will be determined by your visa type and if you meet certain IRS tests - Green Card Test or the substantial presence test .

If you do not meet these tests for the first year in the USA, you will be considered a nonresident alien and will file a Form 1040NR which is not supported by TurboTax. Here is a link to the IRS website for Form 1040NR, U.S. Nonresident Alien Income Tax Return.

If you are a Nonresident Alien who will become a Resident Alien under the Substantial Presence test in the year following this taxable year, you may elect to be treated as a Dual Status Alien for this taxable year and a Resident Alien for the next taxable year if you meet certain tests. Refer to the First Year Choice area, under Dual-Status Aliens, of Chapter 1 in Publication 519, U.S. Tax Guide for Aliens.

If you meet the Green Card Test or the substantial presence test for this year, you will be considered a dual-status alien. In this situation, you would report only US sourced income before the date of your residency and all worldwide income after the date of your residency. (TurboTax does not support dual status filings.)
