U.S.-based online car service Uber is facing another roadblock on its way to dominating worldwide as its Portland operation is suspended for the next three months.

Uber announced Thursday that their operation will be hold starting Sunday evening until April 9 while city officials revise its regulations in compliance with safety and consumer protection rules, Cnet reports.

The agreement made by Uber and Portland came after the city sued the ride-sharing company for violating the city laws when UberX service began. It is reported that the city's regulations for car services are not always being met by Uber's drivers, which led them into the said agreement.

This kind of scenario is not something new to Uber as the company has consistently offered its services to new markets without getting permission from city officials, The New York Times reported.

Uber, which operates in 60 cities across 21 countries, faced a lot of controversies and bans just this year. Just this month alone, Spain, Thailand, The Netherlands and New Delhi sued Uber.

Spain blocked Uber after a taxi association filed a complaint against the company for not being properly licensed, in which, they think, is unfair to competition. On the other hand, New Delhi shut down Uber due to an allegedly rape incident involving one of its drivers.

The Netherlands also banned Uber due to licensing issue. Same goes with Thailand, officials said that their driver's carry improper licenses; their rates were not approved and their car's were not properly registered.

Despite all these stumbling block being faced by Uber, the company is still in its full force and a lot of big names are still investing to this fast-growing company.
