Third-country
nationals, posted to Belgium, can be authorised to stay for an unlimited
period. Practically, the Immigration Office, based on its discretionary power,
issues to long-term posted workers, residence permits type B, valid five years.

Such
authorisation can be considered on the one hand as a warning light and on the
other hand as an opportunity. Although a very particular case, it merits
assessment in the light of the national legislation and EU law.

Pursuant to
Article 9.6° Royal Decree of 9 June 1999, third-country nationals, posted, are
eligible for work permit in Belgium, for a duration of maximum eight years.

Article 2
Law of 5 March 2002, implementing 
Directive 2014/67/EU (on the enforcement of Directive 97/71/EC),
provides for the definition of “posted worker” (“for a limited period , carries out his work in Belgium”) and for
the assessment criteria to determine whether the worker temporarily carries out
his or her work in Belgium, inter alia, whether “the work is carried out for a limited period of time” , “the date on which the posting starts” and
whether “ the posted worker returns to or
is expected to resume working in the country from which he or she is posted”.

According
to the case law of the ECJ, on the one hand,  the maximum duration beyond which a supply of
service can no longer be regarded as a provision of services, cannot be
determined in an abstract manner (judgment of 11.12.2003, case C-215/01,
Schnitzer, rec. 28 and 31. cf. judgment of 30.11.1995, C-55/94, Gebhard), and
on the other hand, “an activity carried
out on a permanent basis, or at least without a foreseeable limit to its
duration, does not fall within the Community provisions concerning the
provision of services” (see inter alia judgment of 7.9.2004, case C-456/02,
Trojani, rec. 28).

It must be
observed that Article 2 Law of 5 March 2002, does not distinguishes between
intra-EU mobility and workers posted by an undertaking established out of the
Community. Pursuant to Directive 96/71/EC, the latter cannot be given a more
favourable treatment. However, the EU law does not preclude Member States from
imposing less favourable conditions to undertakings established out of the
Community.

Pursuant to
Article 4.4 Directive 2014/67/EU, the failure to satisfy one or more of the criteria
determining whether a posted worker temporarily carries out his or her activity
in the host country, “shall not
automatically preclude a situation from being characterised as one of posting”.
Although not transposed into the national legislation, as far as intra-EU
mobility is concerned, the provision has direct effect (i.e. can be enforced by
individuals in their national courts). Depriving undertakings established out
of the Community from the right to enforce such provision, has no intrinsic
connection with the rights determined by Directive 2014/67/EU, and as a
consequence, in determining whether a third-country national posted,
temporarily carries out his or her work in Belgium, the authority has the
discretionary power to consider exclusively one or several criteria.

It must be
noted that the social security subjection is not a criterion in determining whether
the worker temporarily carries out his or her work in Belgium. Pursuant to
social security agreements entered between Belgium and certain third-countries,
the social security subjection in the country of employment is limited to a
period below or equal to five years. However, in certain cases, the competent
authorities may agree that the employee remains subject to the social security
in the employment country, beyond such period. Nationals of countries that have
not entered a social security agreement with Belgium, cannot be subjected to
the local social security system.

Having
regard to the above considerations, third-country nationals posted to Belgium
and authorised to stay for an unlimited period, should avail themselves of the
opportunity to take local employment (being exempt of the obligation to hold a
work permit), or merely resume working in the country from which they are
posted.

It is hard
to allege that after a long-term posting, a worker authorised to stay for an
unlimited period, may qualify under the definition of “posted worker “as provided
for by the Law of 5 March 2002.

More ever, the
authority may decide to assess the case in the light of Article 4.5 Directive
2014/67/EU and the national legislation on hiring out of workers (notably the
Law of 24 July 1987 amended by the Laws of 13 February 1998 and 12 August 2000,
and the Programme Law of 27 December 2012).
