Lawmakers are to hold a special meeting to inquire into the wrongful jailing of Lin Qiaoying.
But the date has not yet been finalised.
The lawmakers are planning to hold a special meeting of the Legislative Council security panel next Thursday following widespread concern sparked by Qiaoying's case.
But the Government has suggested they convene the meeting on February 21 for the administration to provide information.
A government spokesman said: 'More time is needed for progress to be made in work currently being carried out by the police and Immigration Department.
'This is a very serious matter over which we ought to act most attentively but not in haste.' Panel chairman Democrat James To Kun-sun said the meeting would still be held if most members could attend.
'We have questions to ask even if they would not be able to provide substantive information,' Mr To said. 'They can still answer questions about the video taping of the interview.
'Some members were eager to hold the meeting as soon as possible. We need a timely monitoring of what concerns the public.' He said five out of nine panel members had said they would attend the meeting and he would telephone other members today to collect their preferences on a date for the meeting.
