@besito89 ,
(a) you can always file as Married Filing Sep ( if you are filing as a Resident for Tax purposes). This is true especially if your spouse does NOT have any income ( world income) --- note that his immigration status ( dependent visa ) is the same as your yours. TurboTax will give you trouble though because even for MFS ( Married Filing Separately ) it will still ask for spouse's details --- you have prepare using dummy SSN, print the return, replace dummy SSN with " N R A" and file by mail. But you can use standard deduction for a single person
(b) When did you enter the country --- 2016 ? Which country are from ( both from the same ? )? There may be tax treaty benefits -- would not know till I know which country you are from
I will circle back once I hear from you
adios
