Asked specifically if a second referendum was possible before Brexit, she said: "Anything in life is possible".
The First Minister is committed to updating Scots about when she might seek to have such a vote later this year, when more details about Brexit are known.
"Scotland is a welcoming country - our prosperity and our public services depend on it".
"If Westminster can not or will not act in our best interests, it is time that our own parliament was able to do so".
But she pulled back from that after last year's snap general election, which saw the SNP lose 21 of the seats it had won in Westminster just two years before.
Sturgeon reiterated calls for the devolution of migration powers to end the UK Government's hostile environment policy towards migrants and refugees, and she focused her ire towards Foreign Secretary Boris Johnson in particular, stating that he wasn't fit for office.

"She is out of touch and leading a divided party".
After being announced as the victor, Mr Brown urged activists to "get ready" for a second independence referendum. Scotland voted to stay in the European Union but, because a majority of Britons as a whole voted in favor of Brexit, it will nevertheless leave.
And he told the conference that Scottish government was willing to compromise with the United Kingdom government over the EU Withdrawal Bill - but not at any price.
"I don't know where it takes us if they are prepared to rip up this convention", Ms Sturgeon said.
She told BBC Scotland the move would be "unprecedented" and would put the country into "uncharted" constitutional territory.
The spokesperson was keen to emphasise that the SNP leader was focused on governing Scotland, saying the speech was "jam packed with day job stuff".
