Thailand's National Council for Peace and Order gave her permission to leave the country on the European trip until August 10.
Ms Yingluck left Bangkok in late July for holiday and to attend the 65th birthday party of her elder brother Thaksin Shinawatra, self-exiled former prime minister, in Paris on July 26.
Thailand's first female prime minister was removed from office in a controversial court ruling before the army seized power in May after several months of street protests and related violence.
The National Anti-Corruption Commission (NACC) on August 5 forwarded her case to the Office of the Attorney-General (OAG), recommending that Ms Yingluck be indicted in the Supreme Court's Criminal Division for Holders of Political Positions.
The NACC advised that she be indicted for dereliction of duty in failing to deal with corruption and losses in the rice-pledging scheme.
The Commission said there were sufficient grounds to the allegations that Ms Yingluck was negligent in failing to scrap the scheme, despite knowing it was plagued by corruption and losses.
Ms Yingluck has criticised the Anti-Corruption agency for unfair treatment, and has requested additional defence witnesses, but they were denied by the NACC.
