Shara, a citizen of Lebanon, receives substantial income from oil holdings in Yemen. She had never visited the United States before her $21$st birthday. That year, Shara visited the United States from March $1$ through June $30.$ In Year $2,$ she visits the United States from April $1$ through August $20,$ and she is also cons uering a $5-$day trip to the United States during the month of October.

a$.$ As Shara's tax advisor, do you think that she should make the trip in October? Assume that she does not meet the closer connection exception and that all months contain $30$ days.

b$.$ Would your answer change if Shara held a green card?
