Saakashvili, who is married to a Dutch woman, told AFP "we are going to continue the fight," once again denouncing what he called Monday's "brutal kidnapping" by Ukrainian authorities.
In the latest chapter of a high-profile, months-long saga, the opposition leader was arrested by masked men in a Kiev restaurant and swiftly deported to Poland.
He has already been successively stripped of both his Georgian and Ukrainian nationalities, rendering him stateless.
On Wednesday, he spoke briefly to AFP outside the offices of the immigration authorities in Rotterdam, where his lawyer said he was sorting out his residency permit.
"Right now I am here, and I will be here for the time being," Saakashvili, 50, said asked if he was planning to stay in the Netherlands.
'A million on the streets'
At a press conference in Warsaw on Tuesday, Saakashvili said he had been blindfolded and rushed first by van, then by helicopter to Kiev international airport.
"I want to stay a Ukrainian politician and fight the corruption. When we have one million (people) in Kiev in the streets, we will go peacefully to Ukraine," Saakashvili told reporters.
He added he was counting on help from supporters to return to Ukraine "to fight corruption".
A former governor of Ukraine's Odessa region, Saakashvili was once an ally of Ukrainian President Petro Poroshenko, but became one of his greatest foes.
Kiev now accuses Saakashvili of trying to stage a coup sponsored by allies of former Kremlin-backed Ukrainian president Viktor Yanukovych -- a charge he strongly denies.
The ugly falling out saw Saakashvili stripped of his Ukrainian passport.
But authorities in the Netherlands said in December that he can apply for a Dutch passport because of his marriage to Dutch citizen, Sandra Roelofs. The couple also has two sons.
In September, Saakashvili defied the Ukrainian authorities and forced his way back into the conflict-riven country across the border from Poland with the help of supporters.
Europe tour?
His party, the Movement of New Forces, has held rallies calling for Poroshenko's ouster and accused the Ukrainian leader of failing to fight corruption.
But it is supported by less than two percent of the population, according to a recent poll.
Sociologist Iryna Bekeshkina, head of the Kiev-based Democratic Initiatives foundation, told AFP "many Ukrainians share the demands" of the protests led by Saakashvili's party.
"But Saakashvili's personality -- a flighty, unpredictable, psychologically unstable man -- scares people away," she said.
The brutality of the arrest which saw Ukrainian border guards push Saakashvili to the ground, insulting and pulling him by the hair, according to footage posted online, has however triggered strong criticism.
The arrest could have a "negative impact" on Poroshenko's image abroad, said Sergiy Solodkyi, deputy director of the Kiev-based New Europe think-tank.
The European Commission has already vowed to continue "to follow developments regarding Saakashvili."
"We expect the rule of law as well as the rights of Saakashvili to be upheld," Commission spokeswoman Maja Kocijancic said.
He is also wanted by authorities in Georgia on charges of abuse in office -- which he also strenuously denies.
Saakashvili said in Warsaw he wanted to visit the Netherlands next "to see my sons," who like his wife are Dutch citizens.
He then plans to "go on a tour of Europe" to gain political support for his cause.
His lawyer Oscar Hammerstein told AFP Saakashvili "did not know that the Netherlands and Rotterdam are so pretty."
"He is very happy here, and thinks it's fantastic," Hammerstein added.
